WASHINGTON (REUTERS) - The US Senate's longest-serving member, Democrat Patrick Leahy, will preside over the upcoming impeachment trial of former President Donald Trump, Mr Leahy said on Monday (Jan 25).
US Chief Justice John Roberts presided at Mr Trump's first impeachment trial last year, as the Constitution requires in presidential impeachments. But senators can preside when the person being impeached is not the current president of the United States, a Senate source said, speaking on condition of anonymity.
Mr Leahy, 80, a lawmaker from Vermont who took office in 1975, is the senator with the most seniority in either party.
"When I preside over the impeachment trial of former President Donald Trump, I will not waver from my constitutional and sworn obligations to administer the trial with fairness, in accordance with the Constitution and the laws," Mr Leahy said in a statement.
The US House of Representatives on Monday will deliver an article of impeachment to the Senate, accusing Mr Trump of inciting insurrection in a fiery speech to his followers before this month's deadly attack on the Capitol. But the trial is not expected to get started until Feb 9.
Mr Leahy is the president pro tempore of the Senate, meaning he is empowered to preside over Senate sessions in the absence of Vice-President Kamala Harris. That duty is usually rotated, however, among senators of the majority party.
Being president pro tempore also makes Mr Leahy, who is the senior member of the Senate Judiciary Committee, the third in line of presidential succession, after the vice-president and speaker of the House.
