Giuliani rebutted Republican Senator Mitt Romney, who said in a statement on Twitter that he was "sickened" by the findings in the report that cited details on how the Trump campaign welcomed political dirt from Russia. Giuliani said Romney should "stop the bull", saying that accepting negative information about a political opponent is common. "I would have advised, just out of excess of caution, don't do it," he said. Nevertheless, "there's no crime".

Trump, who spent the holiday weekend at his private Mar-a-Lago resort in Palm Beach, Florida, asserted in tweets on Sunday that he had been fully cleared by Mueller's report and that Democrats' continued efforts to investigate him will prove politically costly.

This is costing our Country greatly, and will cost the Dems big time in 2020!" he tweeted. Mueller explicitly did not exonerate Trump in the report on the question of obstruction, citing in part Justice Department guidelines that a sitting president shouldn't be indicted. Not ruling out impeachment, Democrat Jerrold Nadler, who chairs the House committee that would hold impeachment hearings, said he remained puzzled why Mueller did not bring charges of criminal conspiracy against those in the Trump Tower meeting. "All you have to prove for conspiracy is that they entered into a meeting of the minds to do something wrong and had one overt act. They entered into a meeting of the minds to attend a meeting to get stolen material on Hillary [Clinton]. They went to the meeting. That's conspiracy right there," said Nadler.

Nadler said it was now up to Congress to investigate after the special counsel said it did not establish enough evidence to bring charges of criminal conspiracy, yet detailed 10 allegations of Trump's attempts to obstruct the Russia investigation that left open whether Trump broke the law. Asked whether the offences were impeachable, Nadler told NBC, "If proven, some of this would be impeachable, yes." He said Democrats' current focus is to "go where the evidence leads us." Nadler has subpoenaed the Justice Department for the full, unredacted report and said he was adding former White House counsel Don McGahn to the list of people he would call to testify before his committee, along with Mueller and Attorney-General William Barr. According to the special counsel's report, McGahn was among the Trump aides who effectively halted Trump's efforts to influence the Russia investigation, rebuffing his demand to set Mueller's firing in motion. Nadler has said he expects the Justice Department to comply with the subpoena for the full report by May 1, the same day Barr is to testify before a Senate committee and one day before Barr is to appear before Nadler's panel. Nadler summoned Mueller to testify by May 23. Democratic leaders are under mounting pressure from the party's rising stars and some 2020 presidential contenders, including Senator Elizabeth Warren and Julian Castro, a former Housing and Urban Development secretary, to start impeachment proceedings.

Loading House Speaker Nancy Pelosi is pushing for a step-by-step approach to the House's oversight of Trump and has refused to consider impeachment without public support and Republican support. Pelosi is convening House Democrats on Monday to assess next steps. Senator Mike Lee, a member of the Judiciary Committee, said it would be a "mistake" for Democrats to pursue further investigations that could lead to impeachment proceedings, arguing that the American public won't stand for it after Mueller failed to conclude that crimes had been committed. "It's time to move on," said Lee, a Republican. Giuliani said Trump's legal team was weighing whether it would release a detailed written rebuttal to the Mueller report.
