Sean Curran, a Secret Service agent who has been working to protect President Donald Trump for years and who was with him during last summer’s assassination attempt in Butler, Pennsylvania, is now the director of the agency.

President Donald Trump used his address to a joint session of Congress on Tuesday to unveil a new member of the U.S. Secret Service -- a 13-year-old brain cancer survivor named DJ.

Sean Curran was officially sworn in as the new Director of the United States Secret Service on Monday. Curran’s swearing-in was held in the Oval Office and was attended by US President Donald Trump and Homeland Security Secretary Kristi Noem.
