Senator Patrick Leahy, not Chief Justice John Roberts, will lead the upcoming impeachment trial of former President Donald Trump.

Leahy, of Vermont, is the interim president of the Senate and the longest-serving active Democrat in the chamber.

“In leading the impeachment process of former President Donald Trump, I will not stray from my constitutional and affidavit to administer the process fairly according to the constitution and the law,” Leahy said in a statement.

The President of the Senate temporarily leads impeachment proceedings against non-presidents. Usually the Chief Justice of the United States conducts impeachment proceedings against the President.

The trial is scheduled for the week of February 8th. The house is expected to submit the impeachment item to the Senate on Monday evening.

The House voted to indict Trump earlier this month, accusing him of instigating a riot. Hundreds of Trump supporters marched into the U.S. Capitol on January 6, shortly after the then-president called for them at a rally to continue to oppose the legitimate results of the presidential election he lost to Joe Biden.

Roberts led Trump’s first impeachment trial about a year ago. Trump was acquitted in the process.
