The Note: All the president’s men line up against special prosecutor Trump is shuffling his legal team.

 -- WHAT YOU NEED TO KNOW TODAY

It's quite the round robin of investigations: Special counsel Robert Mueller is digging into President Donald Trump's business dealings, Bloomberg reported a day after Trump told The New York Times if Mueller does so, it's crossing a red line.

Trump's attorneys and aides are investigating Mueller's team in hopes of uncovering any conflicts of interests to undercut the Russia probe, The Washington Post and The New York Times reported.

Trump has also been asking about his authority to pardon his associates, his family and even himself, The Washington Post said.

Meanwhile, Trump is shuffling his legal team: Ty Cobb takes the lead from Marc Kasowitz, while spokesman Mark Corallo resigned Thursday night.

And the tension will continue: After Trump criticized him in the New York Times interview, Attorney General Jeff Sessions said Thursday he's not going anywhere ... "so long as it's appropriate."

A new addition to the Trump team: Trump is expected to announce Wall Street's Anthony Scaramucci as the new White House communications director.

THE TAKE with ABC News' Rick Klein

Call it a reshuffling, or a shakeup, or a simple expansion of the team. Just don't call it an effective new strategy, not until certain other behaviors are moderated or changed altogether. Moving people around in the communications operation and the legal team suggests that President Trump's problems have stemmed from either the communications or legal advice he's getting. But it's his own behavior – from hiring Michael Flynn to firing James Comey, denouncing the special counsel's "witch hunt" and slamming the nation's three top law enforcement officials – that lie at the heart of the swirling controversies his aides and advisers are trying to calm. With talk of pardons and of undercutting special counsel Robert Mueller's team, not to mention his unprecedented public brushback of his own Justice Department, a president who respects no boundaries seems to be daring those investigating his activities to go further, with behavior that would not be tolerated in an underling. Bringing in new people won't make it easier for spokespeople to explain the inexplicable, or for lawyers to defend the indefensible.

QUOTE OF THE DAY

"I don't even pay any attention to what is going on with the administration because I don't care. They're a distraction. The family is a distraction, the president is a distraction." -- Rep. Mike Simpson, R-Idaho, to Politico

COULD CLIMATE CHANGE BECOME A VOTING ISSUE?

Global warming warrior and former Vice President Al Gore said Thursday there might be a silver lining to President Trump's decision to pull out of the Paris Climate Agreement. "For every action there is an equal and opposite reaction," he said, citing a law of physics. "What we are seeing in the United States of America today is the biggest upsurge in favor of the climate that we have ever experienced, and it is in reaction to what President Trump has said." Gore listed U.S. governors and mayors who, in the wake of the announcement from the White House, have made their commitments to expand renewable energy and curb greenhouse gas emissions locally. "And we're seeing it around the world, where countries have doubled-down on their commitment to the Paris Agreement," he went on. During a Sirius XM town hall promoting his new movie, he added it was as if the president's announcement lit a fire under world leaders who are now saying they will meet their energy and environmental goals even faster, just to show up Trump, ABC News' MaryAlice Parks reports.
