Nobles said an official told him the person was "disturbed in some way" and "had a letter" he was trying to deliver to someone in the White House.
President Trump is in Florida. The letter was intended from someone who works at the White House and not the president himself. The agency said it was still investigating and had put additional security posts, technology enhancements and new response protocols into place.
President Trump, who was at the White House at the time of the breach, applauded the Secret Service's arrest of Tran as a "fantastic job".
Tran stated he had jumped the fence and added, "I am a friend of the president", Secret Service officer Wayne Azevedo wrote in an affidavit.

Despite spending a lengthy time on the White House grounds, the Secret Serviced confirmed that "at no time did the individual gain entry into the White House". He then scaled another 8-foot vehicle gate and another 3.5-foot fence in the southeast corner of the East Wing of the White House, according to the Secret Service. He even reportedly tried to jiggle a doorknob to get into the White House while President Trump, 70, was home!
It wasn't until 11:38 p.m. EST that uniformed Secret Service agents located and apprehended Tran. "It's just beyond comprehension, especially because it's not the first time this has happened", he said. "I don't know what in the world they're doing but it is a total and complete embarrassment".
Chaffetz told Blitzer Friday that he was not sure whether the White House doors were locked when Tran allegedly approached them, but "the intruder did not get into the White House".
The Secret Service was criticized for playing down the severity of the episode until a fuller account emerged in an investigation by a House subcommittee led by Chaffetz.
