January 25: The House Intelligence Committee, chaired by U.S. Rep. Devin Nunes (R-Calif.), announces its intent to investigate Russian meddling.
Mueller is also examining whether Trump has obstructed justice in trying to thwart the Russian Federation investigation.
Reince Priebus, the former White House chief of staff, said Sunday that he "never felt that the president was going to fire the special counsel", disputing a report in The Washington Post that he was "incredibly concerned" Trump was moving to fire Mueller last summer. Schumer says Trump's refusal to back the Democratic memo'srelease would show his intent to undermine the investigation.
If the House Intelligence Committee approves the release of the Democratic memo, it is expected to go to the Justice Department for redactions.
"What is happening in our country is a disgrace", Trump said as he announced the memo.
They are seeking to release a memo of their own making these same points.
"A refusal to release the Schiff memo. will confirm the American people's worst fears that the release of Chairman Nunes' memo was only meant to undermine Special Counsel Bob Mueller's investigation", Schumer wrote on Sunday in a letter to Trump. That clears the way for the House Intelligence Committee to release the document, which is based on classified information and alleges the FBI abused us government surveillance powers in its investigation into Russian election interference.
Jerry Nadler released an analysis Saturday as a rebuttal to the Republican memo, spearheaded by House Intelligence Chairman Devin Nunes, which was released Friday.
The memo contends that the Federal Bureau of Investigation and Department of Justice used information from a dossier on Mr Trump - compiled by a former British spy, commissioned by a research firm called Fusion GPS - to obtain surveillance warrants in 2016 for former Trump campaign adviser Carter Page, and that they did not inform the court that granted the warrant that the Democrats had funded the dossier.
Former FBI Director James Comey publicly slammed the "dishonest and misleading memo" released by House Republicans on Friday, after it was finally declassified by President Donald Trump amid objections, asking his Twitter followers: "That's it?"
The top Democrat on the House Intelligence Committee is slamming the release of a congressional memo that alleges FBI surveillance abuses in an investigation into the Trump campaign's Russian Federation ties.
"I would argue it's also somewhat unprecedented to rely on political opposition research to instruct and inform an application, and it's really bad precedent and unprecedented to not tell a court that a source has this level of bias", said U.S. Rep. Trey Gowdy (R-South Carolina).
Republicans say a judge should have known that "political actors" were involved in allegations that led the Justice Department to believe Page might be an agent of a foreign power - an accusation he has consistently and strenuously denied.
Senator John McCain accused his party colleagues, and Mr Trump, of playing into the hands of Russian President Vladimir Putin.
