The bipartisan House task force investigating the assassination attempt of former President Donald Trump is ramping up its efforts with a sweeping records request to both the Department of Homeland Security and the Secret Service. 

In letters sent to the agencies on Wednesday, the task force requested access to documents detailing the preparation and security decision-making in the hours leading up to the rally as well as agents’ responses once the shooting began. Lawmakers are also pushing for interviews with several Secret Service personnel who were on duty and were responsible for the security detail that day.
