How Joe Neguse and Stacey Plaskett Plan to Wield Their Influence After Impeachment

Mr. Neguse, a graduate from the University of Colorado Law School, worked at a law firm before seeking political office. Ms. Plaskett was a student of Representative Jamie Raskin, Democrat of Maryland and the lead impeachment manager, at American University’s Washington College of Law. A political appointee at the Justice Department under President George W. Bush, she also served as an assistant district attorney in the Bronx and counsel to the House ethics committee before running for Congress.

On a team of nine that had a shared century of legal experience, Mr. Neguse and Ms. Plaskett delivered some of the most powerful moments of the trial. Mr. Neguse helped burnish the argument in favor of the constitutionality of trying a former president and contributed to closing remarks. Ms. Plaskett steered senators through a detailed recounting of the violence and how close it came to them, and she offered a powerful rebuke of the Trump defense team’s use of footage of women of color to equate Mr. Trump’s remarks ahead of the Capitol attack with statements from Democrats.

The swift nature of the trial also intensified the pair’s juggling act of parenthood and their work, still a rarity in Congress. Mr. Neguse’s infant daughter made an appearance on at least one Zoom call with the managers, while at one point Ms. Plaskett had her sixth-grade daughter working on a literature assignment in a back room during the trial when her husband had a meeting.

“‘My sitting here is the combination of so many sacrifices,’” Ms. Plaskett said, reading from a note to herself and her family during the last day of the trial. “‘Always remember that to whom much is given, much is required.’ I didn’t want to forget that.”

Just three dozen lawmakers have served as prosecutors of a president in an impeachment trial, a role that helped vault several to higher office. With impeachment trials historically serving as inherently partisan proceedings, their roles as managers could also open Ms. Plaskett and Mr. Neguse to increasing partisan attacks.

Their political futures are murkier, in part because of the unique circumstances of their respective districts, even as they drew acclaim for their work on impeachment.

While senators in both parties privately predicted that Mr. Neguse would one day join their ranks, it is unlikely that he would mount a primary challenge to either Senator Michael Bennet of Colorado, a Democrat who is up for re-election in 2022, or Senator John Hickenlooper, who just began his six-year term after defeating Cory Gardner in November.

Because the Virgin Islands constitute an American territory, Ms. Plaskett has no vote on the House floor, let alone Senate counterparts.

“I’m hoping to use this position and whatever that means to benefit the people who brought me to that table and to that podium for that impeachment trial,” Ms. Plaskett said. “At the end of the day, that’s the people of the Virgin Islands.”

Even before the pair took on the prosecutorial mantle, Mr. Neguse and Ms. Plaskett had parlayed their experience into more prominent roles within the House Democratic caucus. Mr. Neguse, in his second term, is part of the formal leadership circle of Speaker Nancy Pelosi of California. And just before she was tapped for the role of manager, Ms. Plaskett said, she was still reveling in the news that she would be the first territory representative to sit on the powerful House Ways and Means Committee.

“I’m going to work hard to try to, you know, to talk to folks that have a different worldview than I do and to try to find common ground,” Mr. Neguse said. “We’ve got to figure out a way to work with each other.”
