Biden circulated the four-page document, titled “Arguments in Support of a Summary Impeachment Trial,” on Jan. 5, 1999. In his memo, obtained by POLITICO, Biden cited historical precedents from impeachment cases going back to the establishment of the Senate and asserted “The Senate need not hold a ‘full-blown’ trial.
“The Senate may dismiss articles of impeachment without holding a full trial or taking new evidence. Put another way, the Constitution does not impose on the Senate the duty to hold a trial,” Biden wrote at the time.
The Delaware Democrat added later: “In a number of previous impeachment trials, the Senate has reached the judgment that its constitutional role as a sole trier of impeachments does not require it to take new evidence or hear live witness testimony.”
