The Salahis weren’t the exclusive party crashers. There was a third uninvited guest, reports WaPo’s Reliable Sources.
Ronald Kessler, chief Washington correspondent for Newsmax.com, reported on it first this morning followed by a statement from the Secret Service. All that is known so far is that the crasher is male and wore a tuxedo.
Last August, Kessler released his book, In the President’s Secret Service: Behind the Scenes With Agents in the Line of Fire and the Presidents They Protect.
