House Democrats are pushing forward to quickly impeach President Trump for an unprecedented second time for his role in last week’s mob attack in the U.S. Capitol that briefly halted the Electoral College certification of President-elect Joe Biden’s November victory over the president. House Speaker Nancy Pelosi formally backs impeachment, saying in a letter to her fellow Democrats that she plans to bring impeachment legislation to the House floor. Speaker Pelosi also said she’s giving Vice President Mike Pence 24 hours to invoke the 25th Amendment, whereby members of the president’s Cabinet can elect to remove him from office, before holding a full House vote in the impeachment resolution. More than 200 Democrats of the 435 total House members have so far signed onto the impeachment resolution.
