In this case, President Andrew Johnson had to issue orders to the commanders of the Southern military districts through the General of the Army. The man holding this position at the time was Ulysses S. Grant.
This law was passed by the US Congress due to their fear of Andrew Johnson not following through on the efforts of Reconstruction in the South after the Civil War. Northern politicians knew that Andrew Johnson himself was a Southerner and was very lenient when allowing them back into the United States. To ensure that these states continued to follow the orders of Congress, they had to implement a law that would allow someone else to have power over Reconstruction. That man was Ulysses S Grant, a former military commander of the Union Army.

A new analysis of the rhesus monkey genome, conducted by an international consortium of more than 170 scientists, also shows that humans and macaque monkeys share about 93% of their DNA.
