WASHINGTON — House Speaker Nancy Pelosi announced Thursday that the House is moving forward to draft articles of impeachment against President Donald Trump. ”Our democracy is what is at stake,” Pelosi said. “The president leaves us no choice but to act.” Pelosi delivered the historic announcement as Democrats push toward a vote, possibly before Christmas. With somber tones, drawing on the Constitution and the Founding Fathers, Pelosi stood at the speaker’s office at the Capitol and said she was authorizing the drafting of formal charges “sadly but with confidence and humility.” “The president’s actions have seriously violated the Constitution,” she said.
