President Trump was in Washington and has plans travel to Nashville to give a speech at the American Farm Bureau Federation’s Annual Convention. Though he has spent substantial time during his first year in office away from the White House, he has primarily visited his Florida resort, Mar-a-Lago.

Eric Trump stated on Twitter that the fire was caused by an electrical issue in a cooling tower, and praised the Fire Department’s response.
