EXCLUSIVE — The government watchdog probing the Secret Service’s handling of the assassination attempt against former President Donald Trump was requested Monday to expand the scope of its investigations.

Sen. Roger Marshall (R-KS) asked that the Department of Homeland Security’s Office of Inspector General broaden its investigations to include allegations that requests from the Trump campaign for additional assets were denied by the Secret Service, how the agency assigns duties and responsibilities for protective details, and agency attrition within the past four years.
