Answering questions at the FBI Omaha, Nebraska field office, FBI Director Christopher Wray said Wednesday he couldn't talk about FBI agents searching Mar-a-Lago, the home of former President Donald Trump, but did say that he is "always concerned" about the threats to law enforcement.

"Well, as I'm sure you can appreciate that's not something I can talk about," Wray said, becoming the first senior Justice Department official to decline to comment on the record and on camera about the search of the former president's estate.

Multiple sources confirmed to ABC News that former President Donald Trump's Mar-a-Lago estate was raided by FBI agents on Monday.

The sources told ABC News that the search began at around 10 a.m.
