As a slaveholder and a Democrat, President Andrew Johnson was C) often at odds with Republicans in Congress.
Andrew Jhonson took office upon the assassination of President Abraham Lincoln in 1865 when the American Civil War was coming to its end. One of the characteristics of his four-year term was his strong disagreements with Republicans in Congress.
As the Civil War had ended, Johnson tried to restore the Southern states (The ex-confederate states) to the Union by granting amnesty to most ex-Confederates and allowing the southern states to elect new governments. Most of the governments elected in the states enacted "black codes", as a way to control and repress the freed slaves. The Radicals of the U.S. Congress found Johnson's policies too lenient and disagreed completely.
They also strongly disagreed over equal rights to black people. In 1866, Johnson vetoed a pair of legislation that protected blacks ( Freedmen’s Bureau bill and the Civil Rights bill) and urged Southern states not to ratify the 14th Amendment which granted citizenship to blacks, however it was ratified in 1868.
Over the following years on Johnson' term, tensions didn't cede, and in February 1868, the House of Representatives voted to impeach Johnson for violating several laws. However, in May, he was acquitted of the charges by the Senate.
