Just to clear it up for you guys, only two presidents were impeached by the House of Representatives but acquitted at the trials held by the Senate: Andrew Johnson (trial) and Bill Clinton (trial). The House Judiciary Committee voted on Articles of Impeachment for President Richard Nixon, but he resigned before the full House of Representatives could vote on any articles. Since the entire House did not vote, Nixon was never impeached.
Enough you guys keep saying he was impeached. You've said he was impeached too. Apparently you did need my little history lesson. You're welcome.
