The director of the U.S. Secret Service said Monday he will complete a sweeping overhaul of the agency in the wake of Sunday's second assassination attempt on former President Donald Trump.

Acting Director of the Secret Service Ronald Lowe said The agency said it needed to reassess its investigative methods and that the threat level remained high. Federal and local authorities confirmed Sunday that they had arrested Ryan Wesley Routh, 58, on suspicion of attempting to assassinate the former president at Trump International Golf Course in West Palm Beach, Florida.

“Coming out of Butler, I have ordered a paradigm shift. The Secret Service's defensive approach works and it's sound, and we saw that yesterday,” Rowe said. “But it has given me guidance that we need to reassess what our defensive approach is, given where we are right now in this dynamic threat environment. We need to move away from a reactive model and move to a responsive model.”
