Name of us presidents that have been impeached?

Bill Clinton and Andrew Johnson are the only two US presidents to be impeached, but impeachment is only the first step in the process of removing a president. (Many people think "impeached" means "thrown out of office," but that is not true.) The procedure for removing a president involves both houses of Congress. After first being impeached (which is like being indicted) in the House of Representatives, a vote must then be taken in the US Senate; if a majority of senators agree, then the president is removed. In the cases of Presidents Clinton and Johnson, the Senate did not vote to convict them, so both men finished their terms as president.

How many presidents were born before the US became a country?

I checked from Buchanan to Polk and can safely assume that Lincoln was the youngest of all presidents before him. Johnson is also older than Lincoln; however, Grant and Hayes belong to an entirely younger generation. So I can say that the 15 presidents before Lincoln plus the one president (Johnson) after Lincoln would be: 16 presidents. -Reloque
