The release of the smoking gun tape destroyed Nixon politically. The ten congressmen who had voted against all three articles of impeachment in the House Judiciary Committee announced they would support the impeachment article accusing Nixon of obstructing justice when the articles came up before the full House.[85] Additionally, John Jacob Rhodes, the House leader of Nixon's party, announced that he would vote to impeach, stating that "coverup of criminal activity and misuse of federal agencies can neither be condoned nor tolerated".[86]
On the night of August 7, 1974, Senators Barry Goldwater and Hugh Scott and Congressman Rhodes met with Nixon in the Oval Office. Scott and Rhodes were the Republican leaders in the Senate and House, respectively; Goldwater was brought along as an elder statesman. The three lawmakers told Nixon that his support in Congress had all but disappeared. Rhodes told Nixon that he would face certain impeachment when the articles came up for vote in the full House; indeed, by one estimate, no more than 75 representatives were willing to vote against impeaching Nixon for obstructing justice.[86]
Goldwater and Scott told the president that there were enough votes in the Senate to convict him, and that no more than 15 Senators were willing to vote for acquittal–not even half of the 34 votes he needed to stay in office.
