the republican party, and what she's now vowing. but we do begin tonight with those major changes now in store for the cdc. the head of the cdc announcing a sweeping overhaul in the wake of the handling of this pandemic. a report finding the cdc failed to meet expectations in its covid response. problems now emerging, as well, in the response to the monkeypox outbreak. the nation's top public health agency has long been criticized as too academic and too slow to confront crises in this country. the report finding the cdc's covid recommendations were, quote, confusing and overwhelming, and its website not easy to navigate for the american people. director dr. rochelle walensky herself ordering the review, now promising change. we of course remember the changing guidance on masks and the delay in ramping up the testing. so, tonight, what this all means, and it comes amid a new and important headline involving covid there is news tonight on when millions of americans will have access to the new covid booster, which will help fight

the newest strains of the virus, omicron ba.4 and ba.5. abc's erielle reshef leading us off. >> reporter: tonight, a scathing review of the cdc, finding the agency repeatedly botched its pandemic response and failed to meet the moment of crisis. the cdc long under fire for its guidance on masking and vaccines over the last two years. >> it's just really confusing. so, it's just like this patchwork of different, like, rules. >> it's like, contradicting. it's, like, a lot of stuff going on. don't do this, don't do that, and then we have to listen to both. >> reporter: the cdc's own director, dr. rochelle walensky, calling for the internally initiated review, studying the cdc's handling of the pandemic during both this and the previous administration. the review found the center's covid recommendations "confusing and overwhelming" and its website "not easy to navigate." dr. walensky vowing a major overhaul of the agency. she is also calling for internal staffing changes, and sharing information faster in "plain language, easy to understand."

this comes as millions of americans might soon be able to get the new covid booster, tailored to target the original covid strain and the omicron ba.4 and ba.5 subvariants. white house covid coordinator dr. ashish jha saying those revamped shots could be out in three weeks if the fda and cdc both give the green light. >> these are substantial upgrades in our vaccines and those vaccines are coming very, very soon. >> reporter: those boosters expected to be for those who are 12 years and older for pfizer, and 18 years and older for moderna, with an expectation of the new boosters for younger children to follow. >> so, let's bring in erielle reshef with us tonight. erielle, dr. jha now saying these new boosters could be available in just three weeks time. that's really soon. so, give us a reality check here. do health officials really think it's plausible they'll have the cdc and the fda both signing off on these new boosters in time for families to get this protection as we head into fall, many preparing to go back

indoors and many back in school already. >> reporter: well, david, that is the question. the fda is expected to give its green light in the coming weeks. then the cdc advisory panel will meet and the cdc director is likely to sign off shortly after that. and david, officials say they do believe these new boosters will roll out as early as september. >> and you heard dr. walensky say today they need to move more quickly during these crises, so, we'll see, this is the first test. erielle, thank you. now to the other major headline today, rudy giuliani under oath before a special grand jury in atlanta. prosecutors have told the man once known as america's mayor that he is the target of their criminal investigation into potential criminal meddling in the 2020 presidential election in the state of georgia. so, abc's steve osunsami tonight at the fulton county courthouse in georgia. >> mr. giuliani, when you met with georgia lawmakers, did you lie to them? >> reporter: this was not a trip to georgia -- >> we will not talk about this until it's over. >> reporter: -- that rudy giuliani wanted to make. the man they once called

america's mayor has defined his reputation these last few years with lies about the 2020 election, was put under oath today in this georgia courthouse, where he's the one who's suspected of trying to help steal the vote. he was called here by a special grand jury investigating claims that former president trump and his friends tried to change the election results in georgia, so that trump could win. and there's tape. while testifying before state lawmakers, giuliani made false claims about election fraud, including comments that didn't sit well with black election workers. >> they look like they're passing out dope, not just ballots. and it is quite clear they're stealing votes. >> reporter: he famously claimed that this video showed fulton county election workers producing suitcases of illegal ballots, charges that were invest glat ed and proven fal by state republicans. those same election workers told the january 6th committee that people started threatening to kill them. this investigation here could stretch for months and will lead to a report. it would take another grand jury to decide if anyone faces charges. u.s. senator lindsey graham has

been called to appear, but he's fighting it. the governor of georgia has also been called to appear, but he's fighting it, too. and then, there's the person at the center of this. the former president, who could also be called. david? >> steve osunsami live in georgia tonight. thank you, steve. tonight, former president trump's most outspoken critic suffering a major primary defeat. wyoming congresswoman liz cheney losing to the former president's hand-picked candidate running against cheney, and this was a landslide. showing the strength of the former president in that state. liz cheney, a central figure on the january 6th committee, suggesting she's not done, vowing after this resounding defeat, now the real work begins, she said. and what she said when asked if she'll run now for president. possibly challenging trump if he runs in the republican primary. here's jon karl again tonight. >> reporter: donald trump vowed to take down liz cheney, and he did. his hand-picked candidate in wyoming trouncing her by more

than 37 points. but for cheney, it's now full speed ahead on the next phase of her mission to deny trump a return to power. this after she did what trump has never done -- admit she lost. >> tonight, harriet hageman has received the most votes in this primary. she won. i called her to concede the race. this primary election is over. but now the real work begins. >> reporter: cheney announced today she has set up a new political organization, not just to challenge trump, but also any candidates who deny the truth about the 2020 election. it's a move that pits her against some of the leading figures in her own republican party. >> no american should support election deniers for any position of genuine responsibility, where their refusal to follow the rule of law will corrupt our future. >> we were winning everything. >> reporter: cheney isn't just calling out trump's lies about the election. she accused him of sowing the seeds of more january 6th-like

violence with his attacks on federal agents after the fbi searched his mar-a-lago home. she singled out trump's baseless claim that agents planted evidence. >> this is yet another insidious lie. donald trump knows that voicing these conspiracies will provoke violence and threats of violence. it is entirely foreseeable that the violence will escalate further. yet he and others continue purposely to feed the danger. >> reporter: today, cheney's dire warning to republicans was echoed by former vice president mike pence. >> these attacks on the fbi must stop. calls to defund the fbi are just as wrong as calls to defund the police. >> and jon karl back in washington tonight, just back from wyoming. and jon, former vice president mike pence also making news on another front tonight. he actually said he would consider -- consider testifying before the january 6th committee if he's actually invited before the committee. obviously liz cheney is the vice chair of that committee. you have interviewed cheney

often. she was asked again today if she's thinking about running for president. she said she was thinking about it. but jon, a reality check here, she lost her primary last night by 37 points. she's convinced that outside wyoming there would be greater republican support for her? >> reporter: david, it's hard to see a path forward right now for liz cheney in a party where donald trump remains the most popular figure by far among the party's rank and file voters. but liz cheney has emerged as the most high profile and outspoken critic of donald trump in america, and she sees this as a movement, a battle that she will fight both inside the republican party and outside the party. >> jon karl just back from wyoming where he talked with voters going into that primary last night. jon, thank you. in the meantime, next tonight here, the suspect accused of attacking author salman rushdie speaking from behind bars, saying he's surprised rushdie survived. and what he said when asked if he'd be in contract with iran's revolutionary guard. tonight, the suspect's own

mother now reportedly disowning him. here's eva pilgrim. >> reporter: tonight, for the first time since he was seen attacking famed author salman rushdie, hadi matar is talking, telling "the new york post" in a jailhouse interview he thought he killed him, saying, "when i heard he survived, i was surprised." rushdie, who has faced death threats for decades after publishing his novel, "the satanic verses," was set to give a talk at the chautauqua institution in western new york when matar rushed the stage, allegedly stabbing him more than ten times. matar's own mother reportedly disowning him. while iran has officially denied any involvement, at least one iranian paper called it divine revenge. matar denied being in contact with iran and would not say if he was inspired by ayatollah khomeini's call for rushdie's death. but did say, "i respect the ayatollah. i think he's a great person." and while he admitted he only

"read a kp couple pages" of the book, he did say he watched his lectures online and accused the 75-year-old of being "someone who attacked islam." matar has pleaded not guilty to attempted murder. he's expected in court on friday. david? >> all right, eva pilgrim with us tonight. eva, thank you. now to a troubling new discovery at lake mead, as we continue to report on the climate crisis. tonight, authorities are trying to identify now a fifth set of skeletal remains. the call coming in this week of this newest discovery, found because water levels have fallen to historic lows. lake mead is the largest reservoir on the colorado river and our chief national correspondent matt gutman back on this tonight on this new discovery. >> reporter: the ever-receding waters of lake mead revealing yet another grim find. park rangers and a police dive team recovering a set of human remains on tuesday. >> they've been finding bodies, i feel like every week or so. it's been kind of crazy. >> reporter: they are the fifth human remains to be found in the lake's receding waters since may.

some of the remains from earlier this summer were found in a barrel. authorities believe the victim likely died of a gunshot wound 40 or 50 years ago. they're investigating it as a homicide. and as alarming as these findings are, they reveal something else -- the climate crisis. the lake, a vital source of water for more than 25 million people across several states and mexico, now setting historic low records. and for more than a year, we've been reporting on the drastic changes to lake mead. decades ago, the water level here at lake mead was so high that they were actually worried it would lap over the hoover dam. but tonight, lake mead is just 27% full. more than 70% of the western u.s. experiencing moderate drought conditions or worse, amplified by climate change. and david, authorities say that multiple investigations into those deaths are ongoing, but they also warn that as the waters at lake mead continue to recede, as they are forecast to

do, it's very likely they will find additional human remains there. david? >> and of course we'll stay on all of this. matt gutman, thank you. we turn next tonight to the newest battle over abortion rights in this country, after roe versus wade was overturned. the new firestorm tonight in florida involving the case of a 16-year-old girl, arguing she should be allowed a waiver to get an abortion. the court denying that request, and abc's victor oquendo from florida now. >> reporter: tonight, a 16-year-old girl is at the center of the debate over abortion in this country in the wake of the supreme court's decision to overturn roe v. wade. she's pleading in a florida court to get an abortion, but an appellate court upholding a lower court's ruling that the girl is "not sufficiently mature" enough to terminate her pregnancy. the teen, referred to at jane doe 22-b in court documents, was 10 weeks pregnant. described as "parentless," living with a relative and has a state-appointed guardian. she's asked the judge to waive

the state's parental notification and consent requirement for minors. arguing "she is sufficiently mature" and "is not ready to have a baby," adding her guardian supported her decision. rtired florida judge jeri b. cohen was not involved in these legal proceedings, but presided over countless cases like this over her career. >> if she's forced to carry a child to term that she does not feel she has the emotional, physical or financial capability to do, that could be extremely traumatizing. >> reporter: the girl, who doesn't have a job and is studying for her g.e.d., can make her case again, but time is of the essence. florida republican governor ron desantis signed a 15-week abortion ban into law this year. and as for that 16-year-old girl, a dissenting judge saying if she's able to come back to court and adequately articulate her request, she may still be able to get a waiver for an abortion. david? >> victor oquendo following this case in florida tonight. victor, thank you. next tonight, the fight to help victims of the opioid crisis in this country. a federal judge in cleveland

tonight awarding $650 million in damages to two ohio counties in a landmark lawsuit they won against cvs, walgreens, and walmart, claiming the way those companies distributed opioids to customers caused severe harm to their communities. the money will be used to help fight the continuing opioid crisis and the families destroyed by this in lake and trumbull counties, that's outside cleveland. all three companies say they will appeal this. when we come back here tonight, the new video coming in after that coach was shot and killed on the youth football field. witnesses now accusing a former nfl star of starting the fight. it was that nfl star's brother, another coach, accused of firing the gun. and then, the horrific fall from a drawbridge. a tourist visiting milwaukee. and authorities asking tonight, how did this happen? r degeneratn may lead to severe vision loss. and if you're taking a multivitamin alone, you may be missing a critical piece. preservision. preservision areds 2 contains the only clinically proven nutrient formula recommended by the national eye institute to help reduce the risk of moderate to advanced amd progression.
