"The Special Counsel's report, even in redacted form, outlines substantial evidence that President Trump engaged in obstruction and other abuses", Nadler said in a statement.
Mr Trump told Mike Rogers, director of the National Security Agency, that news stories alleging that Mr Trump's 2016 White House campaign had ties to Russian Federation were false and the president asked whether Mr Rogers could do anything to counter them.
Trump said news stories linking him with Russian Federation were not true and he asked Rogers "if he could do anything to refute the stories".
U.S. Senator Elizabeth Warren became the first major contender for the Democratic 2020 presidential nomination to call for the start of impeachment, saying on Friday that "the severity of this misconduct" demanded it.
The former US presidential Advisor Donald McGahn, one of the key figures in the Russia-investigation by special investigator Robert Mueller, is scheduled to testify before Congress.
Pete Buttigieg, the mayor of South Bend, Indiana, said the best recourse for Trump's actions as president would be to vote him out. We will not let Republicans help Trump bury the truth.
He also said Congress needed to look at Mr Trump's finances and gauge Mr Mueller's intentions with his report. "It is also important to know that the facts regarding holding the president accountable can be gained outside of impeachment hearings".
The special counsel said the evidence did not establish that Trump asked or directed intelligence officials to "stop or interfere with the FBI's Russian Federation investigation". "It was the Democrats that committed the crimes, not your Republican President!"
After Mueller's report was released, the most prominent of the Democratic freshmen, Rep. Alexandria Ocasio-Cortez of NY, signed on to Tlaib's resolution calling for an investigation into Trump's conduct and the question of whether it merits a formal charge in the House. Congressional panels are demanding the unredacted version of the Mueller report and its underlying material gathered from the investigation.
"According to the special counsel report, McGahn responded to the president's request by calling his personal lawyer and his chief of staff, driving to the White House, packing up his belongings and preparing to submit his letter of resignation".
After Trump repeatedly brought up the Russian Federation investigation with his national intelligence director, "Coats said he finally told the President that Coats's job was to provide intelligence and not get involved in investigations", the report said.
Sen. Elizabeth Warren of MA and Julian Castro, a former Housing and Urban Development secretary, are for impeachment proceedings.
"I think that's there definitely a conversation to be had on that subject", Harris said, referring to impeachment, "but first I want to hear from Bob Mueller and really understand what exactly is the evidence that supports the summary that we've been given".
