January 2, 1973
Nixon meets with Mike Mansfield, the Senate Majority Leader (microphones in the wall sconces picked up the entire conversation).
Mansfield tells Nixon about Vietnam: "This is the end of the line." A Democratic House and Senate would vote to cut-off funding if the war was not concluded in January 1973.
Nixon's last word on Congressional interference with the delicate peace negotiations: "Don't let the Senate screw this up."
