The Secret Service on Friday announced that its internal probe of the first assassination attempt on former President Donald Trump found “complacency” among some of its employees who conducted the advance security planning for the July 13 rally that led to protocol breaches.

Secret Service acting Director Ronald Rowe said in a news conference that those employees will be disciplined, but he declined to get into details.

“While some members of the advance team were very diligent, there was complacency on the part of others that led to a breach of security protocols with respect to accountability,” he said.

“The mission assurance review has identified deficiencies in the advanced planning and its implementation by Secret Service personnel,” he said. “These employees will be held accountable, and this agency has among the most robust table of penalties in the entirety of the federal government.”

Mr. Rowe said he couldn’t detail the specific penalties being administered because federal regulations prohibit him from getting into personnel matters as they’re proceeding.
