but first, here's a look at what's on nbc tonight and chuck and i will see you again at 11:00.

an exclusive interview we aired with former mayor rudy guiliani this time on monday has generated lots of controversy online and headlines in the papers. >> now the de blasio administration is pushing back. government affairs reporter melissa russo is here with the latest. >> yeah, shiba and chuck. and former mayor rudy guiliani told me he went to complain about a homeless guy living on his block, he also said he thought it was mean for mayor de blasio to let homeless people live on the streets. the de blasio administration seems to think it's guiliani's approach to the homeless that's mean. >> you can't let them stay on the street. then you chase them. you chase them, and you chase them and you chase them and you chase them. and they either get the treatment they need or you chase them out of the city. >> reporter: former mayor rudy

guiliani says that's how the city should deal with homeless people presenting a public nuisance. but the de blasio administration fired back today, saying, they're engaging in constructive solutions, focused on housing permanency, not chasing people from corner to corner. >> new york city is throwing in everything we've got to solve the homelessness crisis. >> reporter: the mayor has added $1 billion to the budget to help the homeless, including a new plan to send mental health teams to treat them on the street. >> i think that getting to the root of the problem will actually benefit this issue a lot more than just chasing them out. >> reporter: de blasio also created a new government program to help the homeless pay rent and says he has moved 450 people this year who were living on the subways into shelters and homes. >> they're making accommodations to get them off the streets. >> reporter: would you rather de blasio approach? >> guiliani. >> what you need is an aggressive mayor, aggressive police commissioner, and a police department that's proactive.

>> reporter: mary bros that han of the coalition for the homeless said asking guiliani for advice on homelessness is like asking bill cosby to pour your wife a drink. now former governor george pataki has joined the fray, saying he suddenly sees homeless everywhere. >> clearly, the police have been told to back off. clearly they are not focusing on quality of life crimes the way that had been done under rudy and under mike bloomberg. >> reporter: city hall insists it was under mayor bloomberg that homelessness soared. it irritates me when one politician blames the other. just take the appropriate action. >> reporter: mayor bloomberg not commenting today. police commissioner bratton has consistently said that his nypd is being aggressive, and has zero tolerance for quality of life offenses like public urination, one of the things guiliani complained about. but bratton says you can't simply arrest someone for being homeless, as homelessness in and of itself is not a crime. chuck and shiba? >> melissa, thank you.

lester holt joins us now with a look at what's ahead on "nbc nightly news" tonight. >> we're covering the story we woke up to this morning, the horrible shooting in virginia of those two journalists. we're going to take a look at their lives, the bright futures, the promising, exciting futures they had. we're also going to hear from some of their colleagues who carried on with a remarkable professionism face of such a horrible tragedy. and a big part of the story, how the gunman used social media. >> he had a gun and a camera on his cell phone in hand, and posted that, even as it was on the run, made twitter postings and that opens up a question about what we all see on social media, what's acceptable, where the lines are, and how that was dealt with, so we've got a well. >> a lot of folks talking about that tonight, lester. thank you. after getting run out of times square, some costumed characters have moved south now to lower manhattan. more of these characters like mickey and mini mouse have started seeking tips in the battery park area. and that has created a turf war of sorts with the statue of liberty characters who have

worked there for years. many argue this is how they make a living. but others who work in that area don't think it's a good idea. >> we think it's bad, you know, for the parent, for the company. because they want you to come over here and relax and see the views and see the monuments. and everything is not good. >> reporter: mayor de blasio cracked down on these costumed characters, and topless women who take pictures with tourists for tips. more new york city firefighters on their way to the west coast to battle the raging wildfires. governor cuomo deployed a team today. more than 1,000 firefighters responded to contain those flames that have torched 25,000 acres. is it dry here? how are conditions looking here at home, janice? area. no problems here whatsoever. we have delightful weather with low humidity and temperatures cool this morning, feeling like fall.

could be a category 1 storm. meanwhile, southern bahamas, turks and caicos, northeastern dominican republic coastline from puerto rico toward guadeloupe. hurricane watches and warnings in effect. the storm is still churning about. going to bring a lot of heavy rain there. it's a beauty, though, for us this evening and for tomorrow, as well. we're back up to around 80, 82 degrees in midtown. a mix of sun and clouds. nice on friday, as well. and then it starts to heat up. and the humidity returns this weekend. but it looks pretty dry and nice for your outdoor plans. >> thanks, janice. bruce beck straight ahead. >> chuck, oc calls it quits in a place where he wreaked havoc for ten years. coming up in sports, one of the best pass rushers in giants' history retires in front of family friends and teammates. we'll hear from oc u umenyiora. and after being she would lled at the stadium, the yankees try to regroup against the astros in a matinee at the stadium. it's all just ahead on news 4 new york at 6:00.

. osi umenyiora's brilliant nfl career came to a close today. the all-pro defensive end signed a one-day contract with the giants and officially retired from the nfl. umenyiora was big blue's second round draft pick back in 2003 out of little-known troy university. he went on to record 75 sacks with big blue. the fourth-most in franchise history. in ten years with the giants, osi was a quarterback's worst nightmare. he helped the g-men win two super bowl titles. and after spending the last two seasons with the falcons, osi was thrilled to come home and hang up the cleats.

>> you miss everything, man. new york giant. and i wish some of the players that. because, you know, it's easy to think one thing, but once you get the chance to go somewhere else and experience something else, you truly realize what family is. and new york is home for me. i think anybody who has been around here and who has won here would tell you that there's really absolutely nothing like winning here in new york. there's nothing like losing here, too. that's horrible. but winning here is truly an amazing experience. >> nice job today, osi. and his old team is back in action this saturday night right here on nbc 4 new york. it's the giants and jets in the metlife bowl. local bragging rights on the line. coverage begins at 7:00 p.m. in baseball tonight, the rampaging mets look for their sixth straight win in philadelphia. the this afternoon, the yankees and astros played the rubber game of their series at the
