Pls 57 pts and marked if right which u. s. senator cast the deciding vote for acquittal in the impeachment trial of andrew johnson? a edmund ross b jefferson davis c thaddeus stevens d abraham lincoln

A

Explanation:

Senator Edmund Ross of Kansas cast the deciding vote, and for all purposes, he was expected to vote against Johnson, up until the night before the final roll call.

The answer is A. Edmund Ross (he represented Kansas)

Jefferson Davis was the president for the Confederate states

Thaddeus Stevens was part of the House of Representatives not the Congress, therefore he wasn't a senator

Abraham Lincoln didn't have a say in matters like this because he was the president before Johnson and didn't have any power anymore. He also couldn't have done anything in this situation because he's DEAD

Hope this helped!
