Who was Robert E. Lee's president?

Answer 1

He was not a president,but he was an army officer.

When he captured John Brown, he was a Colonel in the US Army, under President Buchanan.

After South Carolina seceded, he was in the service of the new President Lincoln, who offered him the job of General-in-Chief of all the Union armies. He said he would wait to see whether Virginia voted to join the Confederacy.

When it did, he reluctantly turned down Lincoln's offer, resigned from the US Army, and went with his state - volunteering as an officer in the Confederate States Army. In that role, his President was Jefferson Davis.
