What was the main conflict between Presidents Lincoln and Johnson in the Congress over reconstruction?

President Johnson was president in the 1960s. He was not even born yet at the time of the US Civil War, which happened in the 1860s.

^^ OK WOW.

Whoever wrote this is a complete moron. The person asking the question clearly meant Andrew Johnson, our seventeenth president, who was president from 1865-1869. Let's re-take American History, kiddo's.
