 -- THE TAKE with ABC News' Rick Klein

President Trump may be waffling on what he is politically – or, at least, shifting on what he wants to reveal on that topic. But the reactions to his shifts, combined with some outside events, show that he has plenty of company in that regard. Republicans are back to where they thought they'd be when the Trump presidency started. They're suspicious of the president's motives, angry at their own leaders, and facing potential new alignments where Trump will cut deals, either on whims or out of strategy, with unexpected outcomes. Democrats can't believe their sudden good fortune. But that collides with the realization that they actually didn't achieve any policy goals with the spending deal they cut, and that nothing stands as reliable precedent with this president. This weekend, with Steve Bannon and Hillary Clinton giving their first major interviews in a long while, both parties will be confronting figures and episodes from the recent past that highlight those divisions. Trump, meanwhile, can just be Trump – and that can easily include tweeted responses to Bannon and Clinton, to stir things up anew. It's another moment where it's worth remembering that Trump's disruption of the political process runs wide, deep, and still strong.

BERNIE BRUSHES OFF CLINTON AND 2016

Bernie Sanders threw some serious shade last night. He didn't rail against a broken Democratic Party, which could have been easy for him, or talk about any of Hillary Clinton's missteps during her failed campaign. In fact, during an interview with Stephen Colbert, he mostly pivoted away from 2016. Still, with just one line, the Vermont senator offered a strong rebuttal to Clinton's most recent criticism of him. "Secretary Clinton ran against the most unpopular candidate in the history of this country and she lost and was upset about that," the Vermont senator said, brushing off the accusations in her new book that his attacks on her during the primary made it hard for her to unify progressives. Clinton kicks off her book tour this weekend more on the defensive than a week ago. In addition to questions about what happened with Trump, she'll also face questions about her choice to point a finger at Sanders and speak rather condescendingly about his campaign. The fact that she lost last year despite her many advantages is why many Democrats – progressives and moderates -- roll their eyes at anything she has to say now. And plenty of Democrats in the trenches today acknowledge that Sanders, while still hazy on practical policy details, was the driving force behind many of the big ideas they are unifying around today, ABC News' MaryAlice Parks notes.

Campus rape policy under review by the Trump administration. In another example of the Trump administration unwinding Obama-era policy, Education Secretary Betsy DeVos announced Thursday that the department will begin the process of updating guidance for Title IX sexual assault investigations -- a move she said would ensure due process on campus. "One rape is too many...and one person denied due process is too many," she said at George Mason Law School in Virginia.
