The Secret Service is under growing pressure to explain what went wrong in the hours and minutes before a gunman opened fire in an attempted assassination on former President Donald Trump at his Pennsylvania rally on Saturday.
"The Secret Service is working with all involved federal, state and local agencies to understand what happened, how it happened, and how we can prevent an incident like this from ever taking place again," Secret Service Director Kimberly Cheatle said in a statement Monday.
The Secret Service is not substantially changing its security plan for the Republican National Convention, which kicks off Monday, Cheatle said, despite the Saturday shooting.
"I am confident in the security plan our Secret Service RNC coordinator and our partners have put in place, which we have reviewed and strengthened in the wake of Saturday's shooting," Cheatle said.
