The Note: 'Acting' Trump Cabinet to play defense for volatile boss Trump now needs several untested individuals to be effective defenders.

The TAKE with Rick Klein

It's a stranger-than-usual week to be part of the Trump Cabinet.

President Donald Trump is in a housecleaning kind of mood. He is pushing his top deputies in policy directions they aren't necessarily comfortable in and replacing those at the top as he sees fit.

Starting Tuesday, members of his cabinet and other top administration officials will fan out across Capitol Hill for an intense series of hearings on budget requests and all other matters lawmakers may ask about.

Attorney General William Barr will be pressed on the "Obamacare" lawsuit and the Mueller report. The IRS commissioner will be getting tough questions about the request for the president's tax returns. And a range of officials will be pressed about the situation on the southern border.

Thanks to Trump's recent pushes, there is new leadership in place -- or not in place -- at the Department of Homeland Security and the Secret Service. That means an "acting" secretary at DHS in addition to the Defense and Interior departments, the Office of Management and Budget, the United Nations and the Small Business Administration and, lest we forget, an acting White House chief of staff.

Trump thrives off of chaos around him. But a man who demands loyalty from his team now needs several untested individuals to be effective defenders when it's harder to discern what's driving the president himself.

What happens to the NAFTA re-do now?

It's been five months since representatives from the three trading partners finished negotiations on the new United States-Mexico-Canada Agreement. The president has called the updated deal a win, but the new treaty has not been ratified by Congress. Now, there's growing buzz about how difficult that might be to get done this year as both the 2020 race and the president's rhetoric heat up.

What's more, Canada has federal elections coming up in October too and its legislature might feel uncomfortable taking up the deal so close to Canadian voters heading to the polls, especially if American lawmakers voice skepticism.

The longer it goes, the more stakeholders will get anxious and the political ramifications could spiral.

The TIP with John Verhovek

When the Democratic National Committee announced its new standards to qualify for their high-profile primary debates, it clearly meant to keep non-serious candidates off the stage.

Former Sen. Mike Gravel, who ran a contrarian presidential campaign for the Democratic nomination in 2008, announced Monday that he is mounting a new bid in 2020. It's a bid he himself says will ultimately fail, but his sole task is to make the first two debates in order to push his anti-intervention brand of foreign policy.

The octogenarian's campaign has gained a surprisingly fervent Twitter army -- now close to 50,000 total followers -- and if he makes the debate stage, the Democratic Party will have to grapple with the harsh criticism he is likely to lob on a national stage.
