When President Trump makes more changes in his West Wing (insiders suspect August or September, but who knows?), any new faces are likely to be in the mold of Anthony Scaramucci, age 53, the pugilistic Wall Streeter known as "Mooch" who was named White House communications director, beginning Aug. 15.

The announcement: "Scaramucci, a successful entrepreneur, financier, and founder of SkyBridge Capital, ... will oversee the entire communications operation, including message development and strategy. He will report directly to the President." (Usually would report to the chief of staff.)

The President is building a wartime Cabinet, for political and legal war. One longtime ally who's likely to have a more visible, frequent role: Newt Gingrich, husband of Callista Gingrich, Trump's choice for ambassador to the Vatican.

Trump relishes fights, and creates plenty of them. But now he's in a real one, with special counsel Bob Mueller signaling that he plans an expansive, exhaustive investigation aimed at Trump, his relatives, and current and former political lieutenants.

One West Wing confidant says Trump really might dismiss Mueller. So POTUS needs "a group that can fight through what could end up being something quite amazing."

"We're going to see out-and-out political warfare, and not over ... Medicaid," the confidant said.

Be smart: As Matt Miller, the MSNBC contributor and former Obama Justice Department official, tweeted after the revelation that Trump was digging dirt on Mueller and contemplating pardons: "Takeaway from the Post & NYT pieces is we are headed for certain crisis. Trump just will not, cannot allow this investigation to go forward."

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.

With college football on the brink, Monday saw an outpouring of support for playing a fall season from numerous parties, including President Trump, Ohio State coach Ryan Day and Michigan coach Jim Harbaugh.

Yes, but: Monday also saw the Mountain West Conference become the second FBS league to postpone fall sports, and the Big Ten and Pac-12 are expected to make the same decision as early as this morning.

Former President Obama and First Lady Michelle Obama will headline two nights of the Democratic National Convention, according to a full list of speakers released by the party on Tuesday.

Our thought bubble, via Axios' Margaret Talev: It signals how much the Democratic Party is still the party of Barack Obama — and how strongly Biden’s team feels the Obamas can validate his vice presidential choice and energize the party’s base.
