On December 13, the House Judiciary Committee voted along party lines to pass two articles of impeachment: one for abuse of power and one for obstruction of Congress.[599] After debate, the House of Representatives impeached Trump on both articles on December 18.[600]

During the trial in January 2020, the House impeachment managers presented their case for three days. They cited evidence to support charges of abuse of power and obstruction of Congress, and asserted that Trump's actions were exactly what the founding fathers had in mind when they created the Constitution's impeachment process.[601]
Responding over the next three days, Trump's lawyers did not deny the facts as presented in the charges but said Trump had not broken any laws or obstructed Congress.[602] They argued that the impeachment was "constitutionally and legally invalid" because Trump was not charged with a crime and that abuse of power is not an impeachable offense.[602]
On January 31, the Senate voted against allowing subpoenas for witnesses or documents; 51 Republicans formed the majority for this vote.
