The Constitution gives the Senate flexibility on whether and how to hold an impeachment trial.
Now that the House has launched an impeachment probe of President Donald Trump, the Senate should reform its antiquated rules for the looming trial. Under current procedures, a trial produces the worst of both worlds. If the House has a flimsy case, the Senate must still put the country through the wrenching, divisive political spectacle without any opportunity to dismiss the case. But if the House has a strong case, senators must sit silently by without any chance to participate directly in the trial. Allowing a real trial will improve the decision-making over whether to fire Trump and will make the Congress more responsive and accountable to the American people.
With House Democrats suggesting a swift march to impeachment by the end of the year, senators can attend to the defects revealed by President Bill Clinton’s 1998 trial. Those rules give senators a passive role: They cannot reject the House’s decision to send an impeachment over, they must sit and listen to House prosecutors and White House defense lawyers without making a peep, they never see witnesses or documents, and they never make arguments over the facts or the law of conviction, particularly the meaning of “high crimes and misdemeanors.”
Senate majority leader Mitch McConnell announced this week that the Senate will automatically hold the trial if the House impeaches. Some conservative commentators argue that Senate Republicans should instead slow-walk the process. Perhaps they could repeat their success in holding open the seat of Supreme Court Justice Antonin Scalia by refusing to schedule a vote. If Republicans could delay indefinitely, or at least until after the 2020 elections, Trump might never face removal from office at all.
