Here's what we know about security measures at the White House Correspondents' Association dinner

WASHINGTON (AP) — The suspect detained after a shooting at the White House Correspondents' Association dinner is believed to have made it past the outermost layer of security at the event at which President Donald Trump was scheduled to speak because he was a guest of the hotel, officials said Saturday.

The shooting suspect was identified as Cole Tomas Allen, 31, of Torrance, California, two law enforcement officials told the AP. Officials told reporters after the incident that Allen was armed with a shotgun, a handgun and multiple knives.

Security for the annual event is always tight when the president attends, especially given the venue’s history — 45 years ago, the Washington Hilton was the site of an attempted assassination of President Ronald Reagan — and law enforcement argued that their “multi-layered protection” worked as designed. Still, the incident was sure to set off more questions about security around the president and political events in the wake of high-profile acts of political violence in recent years.

The 2,300 guests at the event in the hotel's cavernous subterranean ballroom had to pass through several additional checks to enter the room, including showing tickets to association volunteers and hotel staff and passing through magnetometers manned by the Secret Service and Transportation Security Administration.
