The Note: Amid separation policy controversy, Trump revs up partisan attacks This is a tense, angry, loud, and messy moment in politics.

The TAKE with Rick Klein

This is a tense, angry, loud, and messy moment in politics – and a potentially scary one.

It may be perfectly Trumpian, at least so far as the president is concerned. President Donald Trump thrives on chaos and sharp divisions, and sees this moment – peppered with campaign events, even as it tests his administration’s ability to manage itself – as an opportunity to rev up partisan attacks.

Last week’s retreat on the issue of family separations was tactical and temporary. Now come presidential calls to deport illegal border crossers without "Judges or Court cases" and not "allow all of these people to invade our Country," and incendiary images and phrases coming from prominent Trump supporters.

With Trump campaigning in South Carolina on Monday, it all sets up an uncertain series of House votes this week on immigration, along with court challenges that could throw the new family-separation policy into further confusion.

Trump says he sees a "red wave" coming. Something is stirring, but first will come intense bureaucratic, legal, and intensely personal dramas.

The RUNDOWN with MaryAlice Parks

Primary voters in seven states go to the polls Tuesday. It's the last big primary day until August.

One of those states voting is Oklahoma, where education funding continues to be a major political issue. Last spring, teacher strikes shut down schools in the state for nine days.

Just last week, the Oklahoma State Supreme Court struck down a proposed ballot measure, which would have repealed tax increases (mostly on oil and grass production) the state passed to pay for teacher raises and end the strike.

The justices called the potential referendum misleading.

But the group of Republicans who led the charge to get a repeal vote on the ballot still have a few week to try again.

And some Democrats have quietly wondered if having the measure on the statewide ballot could rally support and help bring voters to the polls.

Candidates have been split on the issue — and not just along party lines. There are a number of Republicans who supported the original bill and did not support the repeal referendum idea.

The TIP with Justin Fishel

The president kicks off this week by once again engaging in South Carolina politics.

He heads to the state Monday to campaign alongside Gov. Henry McMaster.

Last week, Trump tweeted that House Republicans "applauded and laughed" when he ribbed Rep. Mark Sanford, R-S.C., after his primary loss in their closed-door meeting.

But several members of Congress and sources who were in the room have said Trump's comments — calling Sanford "nasty" and saying he wanted to congratulate him on his campaign — fell flat, and were met with silence and a few boos from Sanford's colleagues.

Republican Congressman Ryan Costello of Pennsylvania summed it up this way: "Categorically false."

Speaking to ABC News Friday, Sanford, who is well liked on the Hill, said he thought Trump's comments to Republicans about his primary loss were "surreal," but said he doesn't regret any of his criticisms of Trump.

Sanford was ousted by Trump-endorsed state Rep. Katie Arrington, who was seriously injured in a car accident over the weekend.

Rep. Justin Amash, R-Mich., defended Sanford repeatedly on Twitter, and responded to Trump's tweet Friday: "House Republicans had front row seats to @POTUS’s dazzling display of pettiness and insecurity. Nobody applauded or laughed. People were disgusted."

QUOTE OF THE DAY

"[Democrats] are on record supporting significant border control. And so when the president says that and calls them clowns and losers, how does he expect the Democrats to sit down and work with Republicans on these issues? And so words matter. What the president says matters. And he ought to knock that off." — Arizona Republican Sen. Jeff Flake on "This Week" Sunday regarding Trump blaming Democrats for family separations at the U.S. border.
