A look at Pelosi's team of managers:
INTELLIGENCE COMMITTEE CHAIRMAN ADAM SCHIFF
The California Democrat, 59, led the impeachment investigation into Trump's pressure on Ukraine to announce an investigation into the family of Joe Biden, even as the president held up military aid to the U.S. ally. Schiff is a former federal prosecutor and is especially close to Pelosi.
JUDICIARY COMMITTEE CHAIRMAN JERROLD NADLER
The New York Democrat, 72, wrote the impeachment articles against Trump based on Schiff's investigation report. He also led hearings into former special counsel Robert Mueller's investigation into Russia's 2016 meddling. Pelosi noted that Nadler served as the top Democrat on the Judiciary Subcommittee on Constitution, Civil Rights and Civil Liberties for more than a dozen years.
REP. ZOE LOFGREN
The California Democrat, 72, is a veteran of three presidential impeachment inquires. She was on the Judiciary Committee during the 1998 and 1999 proceedings against President Bill Clinton. She worked for a Democratic congressman from California who served on the Judiciary Committee during the impeachment inquiry against President Richard Nixon. Nixon resigned before he could be impeached.
REP. VAL DEMINGS
The Florida Democrat, 62, is a member of both Schiff's and Nadler's committees, making her one of the House's foremost experts on the case against Trump. She served in the Orlando Police Department for nearly three decades, becoming the first woman to lead it as chief.
REP. HAKEEM JEFFRIES
The New York Democrat, 49, is the chairman of the House Democratic Caucus, putting him in close touch with the sentiment of Pelosi's troops and giving him a seat at her leadership table. He is a corporate lawyer and former state assemblyman.
REP. SYLVIA GARCIA
The Texas Democrat, 69, gives the team some red-state cred and is a member of the freshman class that helped flip the House from Republican control last year. She is a former presiding judge of the Houston Municipal System and a former state senator.
REP. JASON CROW
The Colorado Democrat, 40, is a lawyer and veteran. He was one of the seven Democratic freshmen with national security credentials who signed an op-ed last year calling for impeachment proceedings, clearing the way for Pelosi to launch them.
This story has been corrected to reflect that Rep. Zoe Lofgren worked for a Democratic congressman who was on the House Judiciary Committee during President Richard Nixon's impeachment; Lofgren did not work as a staffer for the committee itself.
