President Donald Trump announced Monday that he had terminated the board of visitors for the U.S. military service academies.

"We will have the strongest Military in History, and that begins by appointing new individuals to these Boards,"Trump wrote on TRUTH Social. 

The order covers the Army, Air Force, Navy and Coast Guard academies.

He said he fired the board members to purge "woke" and "leftist ideologies" from the academies.

Individuals on the boards of visitors are appointed by Congress, the vice president and the president. 

The role of these boards is to "inquire into the state of morale and discipline, the curriculum, instruction, physical equipment, fiscal affairs, academic methods, and other matters relating to the academy," according to the U.S. Naval Academy. 

Those appointed serve three terms, according to The New York Post.
