It's still an open question which House Democratic lawmakers will prosecute the case in the Senate as impeachment managers, which will be selected by House Speaker Nancy Pelosi, though she is expected to name Reps. Adam Schiff and Jerry Nadler, who chair the two committees that spearheaded the impeachment proceedings, as the leaders of the impeachment manager team.

Sources involved in the conversations also believe that Pelosi is looking to select a team that reflects her caucus. Among those being considered are...

Florida Rep. Val Demings

California Rep. Zoe Lofgren

New York Rep. Hakeem Jeffries

Illinois Rep. Raja Krishnamoorthi

Connecticut Rep. Jim Himes

California Rep. Eric Swalwell

Maryland Rep. Jamie Raskin

California Rep. Jackie Speier

Texas Rep. Joaquin Castro

But Democrats say Pelosi has not made any final decision, especially because she doesn't know the makeup of the trial. And she has not informed her colleagues who she is expected to name.

"If the Senate decides we're doing to have a full-blown trial with witnesses and cross examination, that might suggest a certain set of individuals with a certain skill set," said Rep. David Cicilline of Rhode Island. "If instead, the Senate is going to limit it to some legal arguments or some constitutional arguments, that may suggest another set of managers."

The sources say if the Senate is expected to hold a short trial with no witnesses, there will likely be a more limited team. A longer trial would likely to lead to a more robust team.
