Washington (CNN) House Speaker Nancy Pelosi did not write off the possibility of moving on impeachment against President Donald Trump as she explained her continued opposition to formally opening the process.

"It's not off the table," Pelosi said Tuesday, adding, "I don't think you should impeach for political reasons, and I don't think you should not impeach for political reasons."

Pelosi has continued to oppose beginning the impeachment process against Trump as increasing members of the Democratic Party, both on the campaign trail and in her caucus, have voiced support for opening an impeachment inquiry.

CNN previously reported that last week House Judiciary Committee Chairman Jerry Nadler, a New York Democrat, lobbied Pelosi to support an impeachment inquiry, and former Nevada Democratic Sen. Harry Reid, Pelosi's old Senate counterpart, likewise called on the House to move on impeachment.
