LAUREL, Md. (WJZ) — When President Trump arrived in Baltimore on Thursday, part of his security team was well-trained K9s.

An elite K9 unit is part of the Secret Service and is trained at a new $10 million complex in Laurel that has large kennels, a veterinary and laundry room, and spaces modeled after the White House.

The K9s swept the building for explosives in just minutes, a job that would take officers hours to complete.
