One year after the near assassination of Donald Trump, a deep frustration has set in at the Secret Service over the agency’s response to the security failures of that day.

A newly released report found the U.S. Secret Service knew of a threat to President Donald Trump’s life more than a week before an assassination attempt at his Butler rally, but never relayed the information.

The report notes that the threat was labeled "highly classified" by Secret Service officials, but it does not provide any details about what the threat specifically involved.
