Final answer:
Andrew Johnson was impeached and tried in the Senate.
Step-by-step explanation:
In the impeachment process, the House of Representatives initiates the impeachment proceedings by bringing charges against the accused, while the Senate serves as the trial court. Impeachment proceedings require a two-thirds majority in the Senate for a conviction. Johnson was acquitted because the Senate vote was 35 to 19 – just one vote short of the required two-thirds. Impeachment efforts ended thereafter.
The entire process illustrates the checks and balances within the United States government, which separate the powers of the legislative and executive branches.The Senate acts as the judge and decides whether the accused should be removed from office. In the case of Andrew Johnson, he was impeached by the House of Representatives and then tried in the Senate.
