Mueller seeks Trump business papers; another White House shakeup?

In 2017, President Donald Trump said the special counsel would be crossing a red line by looking into his personal finances. It looks like Robert Mueller has crossed that line.

The New York Times reported that Mueller's team is looking for business documents related to Russia. Attorneys for the Trump Organization dismissed the news, saying the company has been cooperating with the Mueller probe for months.

"There was no collusion between the campaign and Russia," White House press secretary Sarah Sanders said.

The administration on Thursday accused Russia of an ongoing operation to hack and spy on the U.S energy grid while separately slapping a barrage of sanctions on Kremlin-linked officials for interfering in the 2016 election.

"It's about time. We've been overdue in imposing sanctions," Sen. Jeff Flake, R-Ariz., said. "So glad to hear."

European leaders are now blaming Moscow for a nerve agent attack on a spy in the United Kingdom.

President Trump said that he, too, is taking it very seriously.

"It's a very sad situation. It certainly looks like the Russians were behind it," Trump said. "Something that should never, ever happen."

After high-profile departures from his administration, including Secretary of State Rex Tillerson and economic advisor Gary Cohn, the Washington Post reported that Trump plans to remove national security advisor H.R. McMaster.

The president downplayed reports more changes are coming. He said changes will always happen and that he likes to hear different ideas.

Some political experts said the recent turmoil in the West Wing could weigh down the commander in chief's ambitions.

"To the extent he has policies he wants to see implemented, he doesn't have the institutional momentum to get these things done," said Wallace Ford, the chair of the Public Administration Department at Medgar Evers College.
