President Andrew Jackson was not impeached; however, he was censured by the U.S. Senate in 1834. President Andrew Johnson was impeached by House of Representatives in February 1868. The Senate convened the impeachment trial against Johnson on March 5, 1868.
Andrew Jackson drew a censure resolution from the Senate over his actions in opposition to the Second Bank of the United States. When he moved the federal government's deposits to state-chartered banks in defiance of Congress' wishes, he triggered a financial panic.
President Andrew Johnson was the first of two presidents to face a Senate impeachment trial. Johnson was impeached over his conduct of post-Civil War reconstruction and his firing of Secretary of War Edwin Stanton. The 11 articles of impeachment at issue in the Senate trial were decided by one vote. Kansas Senator Edmund Ross voted to acquit Johnson, and as a result the Senate failed to achieve the two-thirds majority needed to successfully remove the President from office.
