Maybe Trump had his Andrews mixed up. One can see how he admires the one who came later

[DemocratSinceBirth]

Andrew Johnson (December 29, 1808 – July 31, 1875) was the 17th President of the United States, serving from 1865 to 1869. Johnson became president as he was vice president at the time of the assassination of Abraham Lincoln. A Democrat who ran with Lincoln on the National Union ticket, Johnson came to office as the Civil War concluded. The new president favored quick restoration of the seceded states to the Union. His plans did not give protection to the former slaves, and he came into conflict with the Republican-dominated Congress, culminating in his impeachment by the House of Representatives. The first American president to be impeached, he was acquitted in the Senate by one vote.

1. so Johnson stayed with the Union when Tennessee seceded

but when he became president at the end of the Civil War he identified with the former Confederate states power structure or culture, and did not protect former slaves.
