President Trump “headed home on Saturday to confront a growing political and legal threat, as his top aides tried to contain the fallout from reports that his son-in-law, Jared Kushner, is a focus of investigations into possible collusion between Russia and the president’s campaign and transition teams,” the New York Times reports.

“The White House canceled a presidential trip to Iowa in the coming days and was putting together a damage-control plan to expand the president’s legal team, reorganize his communications staff and wall off a scandal that has jeopardized his agenda and now threatens to engulf his family.”

Also interesting: White House counsel Donald McGahn “has been increasingly uneasy in his role since Mr. Trump ignored his advice to delay Mr. Comey’s dismissal.”

“Amid mounting questions at the White House about Russia, three prominent members of President Trump’s family — his sons Eric Trump and Donald Trump Jr., and Eric’s wife, Lara — have ramped up their engagement with the Republican Party’s national political operation, having met privately with GOP leaders to share their concerns and outlook,” the Washington Post reports.

“Their appearance at the RNC irked at least two prominent Republicans who were briefed on the session, who wondered whether it was appropriate for the president’s sons, who run the Trump family real estate business, to be highly involved in discussing the party’s strategy and resources.”

Mike Allen: “A hot theory is that Trump can’t clean house because those inside know too much to be let go, and outsiders (beyond old campaign hands) can’t be trusted with what they’d learn.”

Politico: “Now that Trump’s current and former aides and allies officially know a probe exists, they’re responsible for preserving all available information that might be relevant. That’s a task complicated by the rise of auto-delete apps like Confide, Signal and WhatsApp, as well as the move his campaign staffers have made into the White House.”

“Hanging over them all: any failure to keep track of emails, messages and other records could expose them to criminal charges down the line.”

President Trump “is actively discussing major changes in the White House, including a shakeup of his senior team, after spending much of his free time during his overseas trip weighing the Russia investigation and the political crisis it poses for him,” the Wall Street Journal reports.

“Meetings devoted to White House operations are scheduled for next week, officials said. Other revisions on the table include a new filter of the president’s social-media habit and fewer scheduled press briefings… The anticipated moves are the latest sign of how the investigation into Russia’s interference in last year’s election, and the circumstances of the president’s firing of FBI Director James Comey, is defining the new administration.”

Said one Trump adviser: “Everything is in play.”

President Trump’s White House “is preparing to establish a ‘war room’ to combat mounting questions about ties between Russia and his presidential campaign… addressing a scandal that has threatened to consume his young presidency,” Reuters reports.

“Upon Trump’s return from a nine-day overseas trip, the administration will add experienced political professionals and possibly lawyers to handle the Russia probe, which has gained new urgency since the Justice Department appointed a special counsel to head the investigation.”

“Respectfully, I’d submit that the president has unearthed some demons. I’ve talked to a number of people about it back home. They say, ‘Well, look, if the president can say whatever, why can’t I say whatever?’ He’s given them license… There is a total weirdness out there.”

“The FBI is investigating an attempted overseas cyberattack against the Trump Organization, summoning President Trump’s sons, Don Jr. and Eric, for an emergency session with the bureau’s cybersecurity agents and representatives of the CIA,” officials tell ABC News.

“Law enforcement officials… confirmed the attempted hack and said the subsequent meeting took place at the FBI’s New York headquarters on May 8, the day before Trump fired FBI director James Comey.”
