On January 22, 2020, the Republican Senate majority rejected amendments proposed by the Democratic minority to call witnesses and subpoena documents; evidence collected during the House impeachment proceedings will be entered into the Senate record automatically unless objected to on a case-by-case basis.
For the three days, January 22–24, the impeachment managers for the House presented their case to the Senate. 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 included an impeachment process in the Constitution. The Trump legal team 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, and thus the president should be immediately acquitted. They did not deny the facts as presented in the charges, but stated that Trump had not broken any laws or obstructed Congress.
