On November 8, 2016, we elected Donald J. Trump to be the 45th President of the United States. Since taking office on January 20, 2017, Trump has had three (3) National Security Advisors. The last one chosen, John Bolton, was a recess appointee of Pres. George W. Bush to be the U.S. Ambassador to the United Nations. His tenure lasted only about 16 months, because he could not survive Congressional questioning.
