HARLOW: Steve Bannon is going after top Republicans. He was in Alabama last night, rallying support for Senate candidate Roy Moore there. Of course, Roy Moore facing multiple allegations of sexual misconduct, assault, and abuse. But Bannon ended up picking fights with Mitt Romney, Jeff Flake, Mitch McConnell, to name a few. Our Kaitlan Collins is in mobile this morning. And when you talk about, you know, a man very close to the president, formerly the chief strategist inside the White House, he laid into Mitt Romney, attacking his kids and his faith.</s>KAITLAN COLLINS, CNN WHITE HOUSE REPORTER: Yes, Poppy. Steve Bannon certainly did not hold back when it came to Mitt Romney here in Alabama last night. Though he was here to rally to get some support for Roy Moore in these last few days before that high-stakes Senate race, he spent a lot of his time focusing on Republicans, and specifically, Mitt Romney. Now, this comes after Mitt Romney has called on Roy Moore to step aside out of this race, after those sexual assault allegations first surfaced and more recently he said that if Roy Moore won, it would be a stain not only on the GOP, but on the nation. And that he didn't think keeping this seat in Republican hands was worth losing the honor or integrity. Well, Steve Bannon didn't take too kindly to that criticism from Mitt Romney, and he claimed that he used his religion to hide behind, to avoid serving in Vietnam.</s>STEVE BANNON, FORMER WHITE HOUSE CHIEF STRATEGIST: You avoided service, brother. You hid behind your religion. You went to France to be a missionary while guys were dying in rice paddies in Vietnam. You had five sons, not one day of service in Afghanistan and Iraq. Judge Roy Moore has more honor and integrity in a pinkie finger than your entire family has in its whole DNA.
