The TAKE with Rick Klein

"I have nothing to hide," President Donald Trump declared in a tweet over the weekend.

"Truth isn't truth," argued his lawyer, Rudy Giuliani.

Underpinning both men's statements is the fact that even now, just two weeks before Labor Day and with the midterms fast approaching, the White House position on the Robert Mueller probe is designed more to enrage than engage.

With Mueller's team seeking its first conviction, and time running out on the latest supposed deadlines for Trump to agree to questioning, the president has returned to his efforts to divide at all costs.

That puts FBI agents, a range of former national security officials and even some past and maybe current aides on the other side of the line being drawn by Trump. In this narrow sense, at least, the president isn't hiding anything at all.

The RUNDOWN with MaryAlice Parks

Trump's National Security Adviser John Bolton had a hard time Sunday explaining the White House's decision to revoke former CIA Director John Brennan's security clearance.

"There is a line and somebody can cross it," Bolton told ABC News' Martha Raddatz during an exclusive interview, without stating whether Brennan was that person nor whether he had done anything explicitly wrong.

The crux of Bolton's argument defending the president's controversial decision was that Brennan may have revealed classified information and should not be in a position to be able to do it again someday.

Of course leaking classified information is a crime, and by talking around the issue with innuendo and suggestion, Bolton causally accused Brennan of something incredibly serious.

"Whether he actually used classified information, I think people will be able to determine," Bolton continued, again, without explanation or examples.

"If there's any kind of misconduct, I think there are lots of grounds to have your security clearance revoked for behavior that calls into question your ability to hold the material in confidence," Bolton went on, skipping over the fact that having a clearance does not mean you have access to classified material, only that you might be able to should the right person in government want you to.

The growing, bipartisan chorus of former intelligence officers who have been speaking out against the move say the decision had nothing really to do with Brennan at all, but was aimed to scare and deter potential critics.

The TIP with Meridith McGraw

"King Trump," "Great Divider in Chief" and "un-American" — those are just some of the ways New York Gov. Andrew Cuomo described Trump over the weekend as they ramped up a war of words.

Cuomo, who faces a Democratic primary on Sept. 13 against Cynthia Nixon, recently did a riff on Trump's "Make America Great Again" slogan that fell flat and caught the attention of the former Manhattanite and president.

"We're not going to make America great again," Cuomo said. "It was never that great."

Trump blasted Cuomo, saying it was a "dumb statement" and potentially "career threatening."

But despite the stumble, Cuomo's rhetoric -- specifically aimed at Trump -- is part of a larger campaign strategy to set up the governor as a foil to the president in a state where his poll numbers aren't so great.

"He's taking on Trump in tough, direct, visceral language that doesn't resort to petty name calling traps other Democrats have fallen into," a Cuomo strategist told ABC News.

"We see this as an opportunity for him to elevate what he's done in New York as an antidote and alternative to what Trump has done as president."
