mishandle while hillary clinton used a private e-mail server while secretary of state. >> although the department of justice makes final decisions on matters like this, we are expressing our view that no charges be pressed in this case. >> reporter: comey confirmed that him clinton had more than one server. discovering in all 113 e-mails containing classified information, eight of them top secret. a picture very different from the one she has described, a blistering attack of her handling of government secrets. was the material marked classified? >> i am confident i never sent nor received any information that was classified at the time it was sent and received. >> any reasonable person insects clinton's position or the position of those with whom she was corresponding with unclassified matters should have known it was no place for that conversation.

>> reporter: was her private server safe from hacking? >> it was on property, guarded by the secret service and there were no security breaches. >> all of these e-mails were housed on unclassified personal servers. not even supported by full time security staff. >> reporter: comey said she sent and received private e-mails to and from her staff while outside the u.s., in countries where hackers thrive while no conclusive proof of hacking was found. comey said the sloppiness did not meet the standards of bringing criminal charges in past cases against her or the former staff members who e-mailed her. past prosecutions he said involved willful mishandling or disloyalty to the u.s. or vast quantities of classified material. a former federal prosecutor agr agrees. >> no charges have ever been brought when there wasn't evidence that someone intentionally mishandled classified information or gave it to someone who wasn't entitled to have it. >> reporter: the fbi's recommendation now goes to the justice department. damage loretta lynch said she will follow the advice of career

prosecutors there and officials say tonight it's a virtual certainty that they will go along with comey's recommendations. >> pete williams. thank you, pete. the fbi announcement came just hours before hillary clinton hit the campaign trail for the first time with president obama. that moment was largely overshadowed as clinton seized on the fbi's findings against her. more on that from andrea mitchell. >> reporter: the fbi's bombshell announcement spoiling what president obama and hillary clinton were hoping would be the political picture of the day, stepping off air force one together, after pointedly not discussing the investigation on the flight down. former rivals now campaigning as a team. clinton even using the rallying cry obama used to defeat her in 2008. >> we are fired up and ready to go, ready to win this election. >> hillary!

>> the fbi backing up -- in a statement concluding we are glad that this matter is now resolved. it's the fbi director's stunning rebuke of clinton. >> there is evidence that they were extremely careless in their handling of very sensitive, highly classified information. >> reporter: that's ready made for republican attacks. donald trump already tweeting, fbi director said crooked hillary compromised our national security. no charges, wow, rigged system. along with a chorus of republicans led by house speaker paul ryan, saying comey's recommendation defies explanation. all this complicating a trust deficit for clinton. in our latest poll, 69% questioning her honesty. >> i personally know i have work to do on this front. >> reporter: clinton hoping the president with a 51% approval rating can help her fix that problem. >> there has never been any man or woman more qualified for this office than hillary clinton.

>> reporter: and take down donald trump. >> everybody can tweet, but nobody actually knows what it takes to do the job until you have sat behind the desk. >> reporter: but today those attacks on trump overshadowed what the fbi director said about clinton. >> he laid out a non-legal but political indictment for republicans to use about what hillary clinton did with her e-mails. >> reporter: all of this spoiling the big democratic rollout in a state obama narrowly lost in 2012, but the clinton campaign still believes they have a good chance of winning despite what happened today. >> andrea mitchell, thank you. fbi director james comey when announcing the agency's finding on clinton did announce how unusal it is to comment on the public investigation. comey is no stranger to such highly charged controversies. kristen welker has more on the fbi boss who stepped back into the spotlight today.

one night in 2004 as then attorney general john ashcroft lay ill in a washington hospital, white house counsel alberto gonzalez and chief of staff, andy card, stood by ashcroft's bedside, seeking his approval of a then secret program to eavesdrop on foreign terrorists. he later told congress -- >> i thought i just witnessed an effort to take advantage of a very sick man. >> reporter: comey has faced a very direct threat of homegrown terror like the attack on orlando three weeks ago. >> we are looking for needles in a haystack. >> reporter: today, the married father of five made yet another mark on history. kristen welker, nbc news. donald trump wasted little time in blasting the fbi's recommendation not to charge clinton calling it quote very very unfair. trump however is facing hiss own -- facing his own controversy after posting an ad

accept the fact and state it in a clear way. anti-semites have no place in this campaign. >> reporter: this morning speaker paul ryan, again forced to distance himself from his nominee -- just like he did after trump's attacks on a federal judge's heritage and an proposed muslim ban. >> sanity semitic statements have no place in a presidential campaign. >> gerald kushner says my father-in-law is an incredibly tolerant person who embraced my judaism since i began dating my wife. i know he does not embrace any such thinking. sweltering temperatures are gripping much of the nation and tonight the heat wave is spreading up the east coast. while in the midwest and plains, thunderstorms are bringing the threat of damaging winds, large hail and potential tornadoes, nbc's blake mccoy has more on these weather extremes.
