Transcript for Sen. Al Franken to resign from Senate amid sexual misconduct allegations
Senator Al Franken announcing he will resign, after multiple allegations of sexual misconduct. And calls from his democratic colleagues, beginning with senate over the last 24 hours, calling on him to resign. But in his own words today, Franken pointed to what he called the irony, the allegations against the current president and against Roy Moore, running for senate, both with strong support from the Republican party. Here tonight, ABC's Mary Bruce. Reporter: Al Franken walking to the senate floor today to announce he's leaving for good. In the coming weeks, I will be resigning as a member of the United States senate. Reporter: Eight women have accused the Minnesota Democrat of sexual misconduct. Franken has apologized for some of his behavior, but today he made one thing clear -- Some of the allegations against me are simply not true. Reporter: Still, he's bowing to the demands of dozens of his democratic colleagues who pushed him to resign. But not without this parting shot, taking aim at president trump and Alabama senate candidate Roy Moore. I, of all people, am aware that there is some irony. In the fact that I am leaving, while a man who has bragged on tame about his history of sexual assault sits in the oval office and a man who has repeatedly preyed on young girls campaigns for the senate with the full support of his party. Reporter: More than a dozen women have accused president trump of sexual misconduct. He ivsists they're all liars. The white house press secretary today defended her boss. I've never felt anything but treated with the highest level of respect and been empowered to do my job. So, I think that's a pretty good start and a pretty good example on that front. Reporter: Republicans are now in a tough spot. The Alabama election is on Tuesday. Moore has denied accusations of inappropriate behavior from eight women, including two who say he assaulted them as teenagers. I'm going to let the people of Alabama make the call. Reporter: Mitch Mcconnell says, if elected, Moore would immediately face an ethics investigation are you concerned here that it looks like the parties are operating by different standards when it comes to sexual harassment? No. Franken didn't have to resign. There was clearly no due process. But when you have everybody coming after you, that's what he chose to do. But -- but that's really up to Franken and up to Moore, not up to the parties. And Mary Bruce with us live tonight up on the hill. Mary, I know there is news breaking right now at this hour about yet another member of congress? What can you tell us? Reporter: David, this time, it is a Republican. We have just learned moments ago that Arizona congressman Trent franks is resigning. He's known as a conservative fire brand, especially on social issues. He now becomes the third member of congress to resign just this week.
