U.S. House of Representatives Democrats are prepared to impeach President Donald Trump if he doesn’t immediately resign, House Speaker Nancy Pelosi said, as the president came under increasing pressure from members of both parties for encouraging a mob that stormed the U.S. Capitol.

Pelosi said Friday that Democrats "will preserve every option” to force Trump from office, either through the 25th Amendment or impeachment. She said she’s instructed the Rules Committee to be ready to move forward with a motion or resolution, but stopped short of saying articles of impeachment would be brought for a vote.

"With great respect, our deliberations will continue,” Pelosi said in a statement. If Democrats follow through, Trump would become the first American president to be impeached twice.
