 Failure, the worst lapse in security in 43 years in US presidential history. There were some claims from Republicans, weren't there, that Mr Trump's security had made a request to be beefed up as a force and they hadn't had that request granted. Those claims have been categorically dismissed by both the Secret Service and the FBI. If they're covering something up, then that'll come back to bite them. But for now, they are certainly saying there's absolutely no truth in those claims.
