President Donald Trump is on the cusp of being impeached by the House, with a historic debate set Wednesday on charges that he abused his power and obstructed Congress ahead of votes that will leave a defining mark on his tenure at the White House. Trump, who would be just the third U.S. president to be impeached, on Tuesday fired off a furious letter to Speaker Nancy Pelosi denouncing the “vicious crusade” against him, but he also acknowledged he was powerless to stop the expected outcome. Pelosi, who warned earlier this year against pursuing a strictly partisan impeachment, nonetheless has the numbers from Democrats to approve it.
