Donald Trump will be travelling to Mississippi on Saturday to attend the opening of a new civil rights museum.

The conference call with the president was an annual tradition under Barack Obama's administration.

Trump defended himself Tuesday by reading out his previous statements on the Charlottesville violence to supporters at a rally, but omitted his most controversial remarks.

The 25th Amendment to the U.S. Constitution allows the vice president to take over if the president is deemed unable to discharge his duties.
