On Tuesday, Senate Majority Leader Mitch McConnell implored his colleagues to cease their inquires into president Donald Trump. In his floor speech, McConnell described the case as “closed,” despite Democrats’ increasing efforts to hold Trump accountable.

“Remember, Russia set out to sow discord, to create chaos in American politics and undermine confidence in our democracy,” McConnell said. “But on that front, given the left’s total fixation on delegitimizing the president — the president Americans chose and shooting any messenger who tells them inconvenient truths, I’m afraid the Russians hardly needed to lift a finger.”

McConnell spent much of his time discussing Russia’s attempts to affect the outcome of the 2016 presidential election, but determined there wasn’t enough evidence to confirm the Trump administration colluded with the hostile power. The Kentucky Republican labeled the Democrats’ inquiries as a “Groundhog Day spectacle,” and questioned why they continue probing. “This ought to be good news for everyone, but my Democratic colleagues seem to be publicly working through the five stages of grief.”

Trump appreciated McConnell’s sentiment, taking to Twitter to quote his fellow conservative:

Minority Leader Chuck Schumer immediately responded to McConnell’s speech, however, calling it “an astounding bit of whitewashing — not unexpected but entirely unconvincing.” Continuing, Schumer said, “It’s sort of like Richard Nixon saying, ‘Let’s move on’ at the height of the investigation of his wrongdoing. Of course he wants to move on. He wants to cover up. He wants to silence.”

House Speaker Nancy Pelosi also drew comparisons between Trump and Nixon. Speaking at an event on Tuesday at Cornell University, Pelosi discussed Trump’s dismissal of congressional subpoenas, something Nixon had done too. “That could be part of an impeachable offense,” Pelosi admitted. “Every day, he’s obstructing justice by saying, ‘This one shouldn’t testify, that one shouldn’t testify,’ and the rest. So he’s making a case. But he’s just trying to goad us into impeachment.”
