Lott and his future Senate colleague, Thad Cochran (also elected to Congress that year), were only the second and third Republicans elected to Congress from Mississippi since Reconstruction (Prentiss Walker was the first in 1964). Lott's strong showing in the polls landed him on the powerful House Judiciary Committee as a freshman, where he voted against all three articles of impeachment drawn up against Nixon during the committee's debate. After Nixon released the infamous "smoking gun" transcripts (which proved Nixon's involvement in the Watergate cover-up), however, Lott announced that he would vote to impeach Nixon when the articles came up for debate before the full House (as did the other Republicans who voted against impeachment in committee).
