A roundup of the day's events. A roundup of the day's events. both officers fire, shooting blevins four times. blevins later dying. at a press conference today, members of a police union said the two officers acted heroically and believed their lives were in danger. >> the whole time, he's looking back, getting position on where the officers are at to acquire a target to shoot them. >> reporter: at a later press conference, the county prosecutor took to the podium to defend the police department. but before he could announce charges would not be filed against the two officers, family and protesters rushed the podium, cutting him off. >> we want the cops arrested within the next 48 hours and prosecuted to the fullest degree of the law, because this was murder. >> and alex perez joins us live tonight from minneapolis. alex, emotions raw there. we saw the family and the protesters at that news conference today. they want justice for their family member. and the city bracing for possible more protests? >> reporter: that's right, david. another demonstration already planned for tomorrow afternoon. family members firmly believe their loved one did not have to die here in this alley. as you heard them say right now, they believe this is murder. david? >> alex perez in minneapolis. alex, thank you. we're going to turn next tonight to president trump and his personal attorney, rudy giuliani, who went on cable tv today. that is not new, but what he said was. after the president has repeatedly said there was no collusion, giuliani now saying collusion is not a crime. abc's chief white house correspondent jonathan karl. >> reporter: when it comes to the russia investigation, there is one message above all where president trump has been perfectly consistent. >> there was no collusion. at all. there was no collusion. at all. everybody knows it. >> reporter: but now, former trump lawyer michael cohen seems to be prepared to tell prosecutors that the president knew in advance about the infamous trump tower meeting organized by donald trump jr. after he'd been promised dirt from the russians on hillary clinton. and today, the president's current lawyer, rudy giuliani, offered a new message. it doesn't matter if the president colluded, because collusion, giuliani says, is not a crime. >> i've been sitting here looking in the federal code trying to find collusion as a crime. >> it's not. >> collusion is not a crime. >> reporter: it's a message giuliani repeated throughout the day. >> you don't even know if that's a crime, colluding about russ russians. >> okay -- >> you start analyzing the krip. the hacking is the crime. the hacking is the crime. >> that certainly is the original crime. >> the president didn't hack. >> of course not. >> he didn't pay them for hacking. >> reporter: giuliani's meandering and confounding interviews followed a series of tweets from the president blasting special counsel robert mueller. "is robert mueller ever going to release his conflicts of interest with respect to president trump," the president tweeted, "including the fact that we had a very nasty and contentious business relationship." the president offered no evidence and did not even say what the conflict was. and neither did giuliani. >> you have every right to say, okay, you explain it, mueller. stand up and be a man. >> why is it up to robert mueller to have to support the president's tweet? >> because he has the conflict, not the president. >> what's the conflict? >> i can't tell you, i'm not sure i know exactly what the conflict is. i have a good idea what it is. it's one that would have kept me out of the investigation. >> reporter: just last month, deputy attorney general rod rosenstein, under oath, told congress he hasn't seen any such conflict of interest. >> i'm not aware of any disqualifying conflict of interest. >> reporter: of course, no word from robert mueller, who is almost never seen in public, although he was spotted at d.c.'s reagan national airport on friday, waiting to board a plane just steps away from donald trump jr. >> and jon karl with us live tonight from the white house. and jon, we know jury selection begins in the trial of paul manafort tomorrow, the first trial, of course, to come out of special counsel robert mueller's investigation. but we heard that argument from giuliani, he has said it before, essentially saying to mueller, if you have something, show us. but is there any sense of when mueller will reveal his findings? what are you hearing from your sources at the white house? >> reporter: well, giuliani himself said that -- based on -- today he said that based on his conversations with robert mueller, he believes that mueller wants to issue his final report on the president by september. but then again, we see the negotiations over an interview between the special counsel and the president have gone nowhere, the president is escalating his attacks, and the bottom line, david, is that nobody but robert mueller really knows how close he is to finishing his investigation. >> all right, jon karl live at the white house. jon, good to have you back. president trump also making news on iran tonight, at his new conference with the italian prime minister today. after ripping up the iran nuclear deal and then exchanging harsh words with the iranian president, today, president trump declaring he would meet, no preconditions, face-to-face, with the iranian president. >> no preconditions. no. they want to meet, i'll meet. any time they want. any time they want. it's good for the country, good for them, good for us. and good for the world. >> not long after that moment, secretary of state mike pompeo indicated there would be preconditions, among them, how iran treats its own people. and when asked, was it true, what iran now claims, that president trump requested a meeting with iran, but iran rebuffed him, pompeo would not answer. we turn next, late today, to cbs' board of directors taking no action against les moonves, at least for now. the chairman and ceo of cbs, he faces new accusations of sexual misconduct. they're instead launching an outside investigation of one of the most powerful men in television and in hollywood. here's abc's eva pilgrim tonight. >> reporter: tonight, the wife of immediaty titan and cbs ceo of les moonves speaking out over sexual misconduct allegations against her husband. >> some of you may be aware of what's been going on in my life over the past few days. i issued the one and only statement i will ever make on this topic on twitter and i will stand by that statement today, tomorrow, forever. >> reporter: in the tweet, chen said, "leslie is a good man and a loving father, devoted husband. he has always been a kind, decent and moral human being. i fully support my husband and stand behind him." "the new yorker" magazine detailing allegations from six women ranging from unwanted advances to sexual assault. actress illeana douglas claiming during a 199 7 business meeting, moonves began violently kissing her, even pulling up her skirt. douglas saying, "i couldn't get him off me." moonves admits to trying to kiss douglas, but denies kissing her, but denies assaulting her, saying in a statement, "i always understood and respected and abided by the principle that no means no." tonight, some conflict inside the company. cbs films president terry press struggling to reconcile the moonves she knows with the allegations, posting this statement. "i do not believe it is my place to question the accounts put forth by the women, but i do find myself asking that if we are examining the industry as it existed decades before through the lens of 2018, should we also discuss a path to learning, reconciliation and forgiveness?" tonight, the cbs board taking no immediate action against the ceo credited with turning around the network, announcing the board will seek to appoint outside counsel to investigate. and david, this independent investigation will be looking at the corporate culture, as well, at the company. david?
