"How do you impeach a Republican President for a crime that was committed by the Democrats? MAKE AMERICA GREAT AGAIN!" Trump tweeted shortly after arriving in Washington following an Easter Sunday spent at Mar-a-Lago in Florida.

Trump's tweet came after several Democratic leaders in Congress made clear on Sunday that the possibility of impeachment was still on the table, despite opposition from Speaker Nancy Pelosi Nancy PelosiHoyer: House should vote on COVID-19 aid — with or without a bipartisan deal Ruth Bader Ginsburg lies in repose at Supreme Court McCarthy threatens motion to oust Pelosi if she moves forward with impeachment MORE (D-Calif.) and others.

The possibility of impeachment gained new urgency after the release of Mueller's redacted report on Thursday. Though the special counsel's team concluded there was no conspiracy between the Trump campaign and Russia, it also outlined in vivid detail ways in which Trump had sought to interfere with the investigation, raising questions over whether he obstructed justice.

Mueller himself declined to draw a conclusion one way or the other on that matter. But the open-ended nature of that section of the report has led to renewed calls by congressional Democrats to look into whether Trump should be impeached.
