Separately, Representative Adam Schiff of California, the ranking Democrat on the House Intelligence Committee, said Trump's tweets had two purposes: to "threaten the FBI director he just fired in the middle of the Russian Federation investigation - and who may now be a witness", and to justify conflicting stories from the White House.
"If they can keep all 52 together, then it won't matter", said Michael Gerhardt, a constitutional law professor at the University of North Carolina-Chapel Hill.
"It stinks", is what Rep. Swalwell said he heard from Rotarians about President Trump's firing of FBI Director James Comey.
Two senior Democrats want Deputy Attorney General Rod Rosenstein to resign if he declines to install a special prosecutor to lead the investigation into Russia's interference in the 2016 presidential election. James Clapper, the former director of national intelligence, said the Founding Fathers created three co-equal branches of government with checks and balances, but with Trump as president, that was now "eroding".

When asked whether he could announce a nominee by Friday, when he is scheduled to leave for the Middle East and Europe on his first trip overseas as president, Trump responded, "Even that is possible".
Said Trump in the statement, "The FBI is one of our nation's most cherished and respected institutions and today will mark a new beginning for our crown jewel of law enforcement".
Under Senate rules, Republicans could confirm an Federal Bureau of Investigation director with 51 votes.
Spicer, who kept his answers short during Friday's briefing and largely dodged specific questions about Trump's meeting with Comey, said he was not aware that any recording of the Trump-Comey meeting exists. They don't overreact; everyone knows the president puts out his own messages. The FBI director also dismisses the president's tweets alleging that Obama ordered Trump Tower to be wiretapped during the election.

A recent survey by the Pew Research Centre marking Trump's first 100 days in office, which was marked on April 29, found that just 39% of the general public approve of the new president. Multiple officials, including Pence, said the president was acting at the behest of Rosenstein and Attorney General Jeff Sessions. Trump said in excerpts of an NBC News interview released Friday that Comey "should have never exonerated" Hillary Clinton.
"These White House tapes could accelerate current investigations as previous tapes have aided past inquiries", Mr. Krishnamoorthi wrote. "I$3 t is a crime to intimidate or threaten any potential witness with the intent to influence, delay, or prevent their official testimony", they say in the letter.
Senate rules requiring unanimous consent or 60-vote thresholds on various procedural or legislative steps give Democrats the ability to slow the Senate to a crawl and delay committee hearings.
Trump's advisers have repeatedly tried to downplay the Russia-election matter, with Sanders saying Wednesday the FBI was "doing a whole lot more than the Russian Federation investigation".More news: US first lady ignores Trump criticism and shuns headscarf
