U.S. Secret Service Protection of Persons and Facilities: Homeland Security Issues in the 116th Congress [March 6, 2019] [open pdf - 502KB]
"Congress has historically legislated and conducted oversight on the U.S. Secret Service (USSS) because of USSS' public mission of protecting individuals such as the President and his family, and the USSS mission of investigating financial crimes. Most recently, the 115th Congress conducted oversight on challenges facing the Service and held hearings on legislation that addressed costs associated with USSS protective detail operations and special agents' pay. These two issues remain pertinent in the 116th Congress due to recent, but failed, attacks on USSS protectees, and the media's and public's attention on the cost the USSS incurs while protecting President Donald Trump and his family."
