House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer (D-N.Y.) are calling for the removal of President Donald Trump following Wednesdays violent insurrection by extremists who were encouraged by Trump.

What happened at the U.S. Capitol yesterday was an insurrection against the United States, incited by the president, Schumer said in a statement Thursday morning. This president should not hold office one day longer.

The Democrat from New York urged Vice President Mike Pence and the rest of Trumps Cabinet to invoke the 25th Amendment, a law that allows the vice president to take over presidential duties if the president is no longer able to do her or his job due to sickness or disability. Once a president is removed under the 25th Amendment, the vice president and Cabinet members can decide if the president is unable to discharge the powers and duties of the White House.

The quickest and most effective way it can be done today to remove this president from office would be for the Vice President to immediately invoke the 25th Amendment, Schumer said. If the Vice President and the Cabinet refuse to stand up, Congress should reconvene to impeach the president.

In her own statement Thursday afternoon, Pelosi also called for the 25th Amendment to be invoked.

In calling for this seditious act, the president has committed an unspeakable assault on our nation and our people, Pelosi said. I join the Senate Democratic leader in calling on the Vice President to remove this president by immediately invoking the 25th Amendment. If the Vice President and cabinet do not act, then Congress may be prepared to move forward with impeachment. That is the overwhelming sentiment of my caucus and the American people, by the way.

On Wednesday, thousands of Trump supporters stormed the Capitol building in Washington, D.C. after Trump gave a speech falsely claiming the election was stolen from him, and encouraging his supporters to march to the Capitol.

Four people were killed in the ensuing violence, including a woman who was shot.
