Opinion Once Trump leaves office, the Senate can’t hold an impeachment trial

J. Michael Luttig served as a judge on the U.S. Court of Appeals for the 4th Circuit from 1991 to 2006.

It appears that even if the House of Representatives impeaches President Trump this week, the Senate trial on that impeachment will not begin until after Trump has left office and President-Elect Biden has become president on Jan. 20. That Senate trial would be unconstitutional.

On Sunday, House Majority Whip James E. Clyburn (D-S.C.) said that, while House Democrats would take up articles of impeachment this week against President Trump, the House might delay sending to the Senate any articles passed by the House until after President-elect Biden’s first 100 days in office. Biden proposed an alternative, under which the new Senate would immediately begin working on his legislative agenda and confirming his Cabinet appointments in the mornings and conduct the impeachment trial in the afternoon.

The sequencing of the House impeachment proceedings before Trump’s departure from office and the inauguration of the new president, followed by a Senate impeachment trial, perhaps months later, raises the question of whether a former president can be impeached after he leaves office.

The Constitution itself answers this question clearly: No, he cannot be. Once Trump’s term ends on Jan. 20, Congress loses its constitutional authority to continue impeachment proceedings against him — even if the House has already approved articles of impeachment.

Therefore, if the House of Representatives were to impeach the president before he leaves office, the Senate could not thereafter convict the former president and disqualify him under the Constitution from future public office.

The reason for this is found in the Constitution itself. Trump would no longer be incumbent in the Office of the President at the time of the delayed Senate proceeding and would no longer be subject to “impeachment conviction” by the Senate, under the Constitution’s Impeachment Clauses. Which is to say that the Senate’s only power under the Constitution is to convict — or not — an incumbent president.

The purpose, text and structure of the Constitution’s Impeachment Clauses confirm this intuitive and common-sense understanding.

The very concept of constitutional impeachment presupposes the impeachment, conviction and removal of a president who is, at the time of his impeachment, an incumbent in the office from which he is removed. Indeed, that was the purpose of the impeachment power, to remove from office a president or other “civil official” before he could further harm the nation from the office he then occupies.

The plain text of the Constitution’s several Impeachment Clauses confirms this understanding of this limit on Congress’ impeachment power. For example, Article II, Section 4 of the Constitution reads, “The President, Vice President and all civil officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.” In the same constitutional vein, Article I, Section 3 provides in relevant part: “Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States.

It has been suggested that the Senate could proceed to try the former president and convict him in an effort to disqualify him from holding public office in the future. This is incorrect because it is a constitutional impeachment of a president that authorizes his constitutional disqualification. If a president has not been constitutionally impeached, then the Senate is without the constitutional power to disqualify him from future office.

Some constitutional scholars take support for their view that the Congress can impeach a former president from two instances in which early Congresses impeached “civil officials” after they had resigned their public offices — the impeachments of Sen. William Blount in 1797 and the impeachment of Secretary of War William Belknap in 1876.

These congressional impeachment cases provide some backing for the argument that Congress can conclude that it has the power under the Constitution to impeach a former president. And Congress’s understanding of its constitutional powers would be a weighty consideration in the ultimate determination whether the Congress does possess such authority. When and if the former president goes to court to challenge his impeachment trial as unconstitutional, Congress is sure to make its argument based on these congressional precedents, as well as others, a case that would almost certainly make its way to the Supreme Court.

In the end, though, only the Supreme Court can answer the question of whether Congress can impeach a president who has left office prior to its attempted impeachment of him. It is highly unlikely the Supreme Court would yield to Congress’s view that it has the power to impeach a president who is no longer in office when the Constitution itself is so clear that it does not.

On the morning of Jan. 6, there were signs of the violence to come even before thousands of former president Donald Trump loyalists besieged the U.S. Capitol. (Video: Joy Sung, Kate Woodsome/The Washington Post, Photo: John Minchillo/AP/The Washington Post)

The riot: On Jan. 6, 2021, a pro-Trump mob stormed the U.S. Capitol in an attempt to stop the certification of the 2020 election results. Five people died on that day or in the immediate aftermath, and 140 police officers were assaulted.

Inside the siege: During the rampage, rioters came perilously close to penetrating the inner sanctums of the building while lawmakers were still there, including former vice president Mike Pence.
