Earlier in the day, National Security Adviser H.R. McMaster denied Trump had caused a "lapse in national security", saying it was "wholly appropriate for the president to share whatever information he thinks is necessary to advance the security of the American people".
"He wanted to make sure he could maintain independence and maintain ethical boundaries", the official said.
"At one level, Putin may find Trump's trials amusing, but he also knows they will make it nearly impossible to restore a modicum of order to Russian-American relations", said Stephen Sestanovich, a senior fellow for Russian and Eurasian studies at the Council on Foreign Relations.
The Comey memo is likely to raise questions about whether Trump tried to interfere with a federal investigation.
Wittes cautioned throughout the interview that his insights into Comey's state of mind were only based on these conversations, and that in some cases he was drawing his own conclusions about Comey's meanings. "They're preserved because he presumes someone will want to see them".
Rosenstein, the No. 2 Justice Department official, named Mueller amid mounting pressure in Congress for an independent investigation beyond existing FBI and congressional probes into the Russian Federation issue.
"He believes that the country deserves answers to critical questions that can only come from an impeachment investigation", said Greg Minchak, a Wisniewski spokesman. "You're getting a little too close to the flame". He went on to say that Comey was widely "unpopular" and that he made the decision to fire the director on Deputy Attorney General Rod Rosenstein's recommendation. It was not immediately clear if he shared the memos with any staffers at a lower level.More news: Almost half of all Hawaii marriages involve interracial couples
It's unclear how much the revelation of the memo factored into Rosenstein's decision to appoint Bob Mueller as special counsel of the Russian Federation probe on Wednesday. The Justice Department declined to comment.
An impeachment by the House is a step toward removing a president, but that alone can not force him to step down. That testimony examined the justification of the firing of eight USA attorneys during the previous year, and called into question whether Gonzales, at that point the attorney general, was fit to run the Justice Department. "I hope you can let this go".
The ACLU today sought the public release of memos reportedly prepared by former FBI Director James Comey that describe his conversations with President Trump.
James Comey was sacked on May 9. After Comey's testimony in 2007, Mueller's notes were subpoenaed by Congress as a way of verifying the account (which Bush and then-White House Counsel Alberto Gonzalez offer a differing version of).
An independent investigation led by a special counsel appointed by the U.S. attorney general would determine if grounds existed for impeachment charges.
The intensifying drama comes as Trump is set to embark Friday on his first foreign trip, which had been optimistically viewed by some aides as an opportunity to reset an administration floundering under an inexperienced president.
