Conservative legal activist group Judicial Watch previously obtained reports of the 10 previous incidents of Commander terrorizing staff from October 2022 through January 2023.

BIDEN'S DOG, MAJOR, BIT SECRET SERVICE MEMBERS FOR 8 DAYS IN ROW, EMAIL SAYS

One of the more serious incidents resulted in the victim, a Secret Service agent, being taken to the hospital after his interaction with the first dog. The victim was bitten on his thigh and arm on Nov. 3, 2022.

In another reported incident, Commander's bite broke the skin of a Secret Service member's hand and arm just weeks after Biden removed his leash outside the White House after a family movie night.

In another attack in January, Commander bit and "latched on" to a security technician's back at Biden's home in Wilmington, Delaware.

Judicial Watch President Tom Fitton said the incidents "raise fundamental questions" about why Biden would "allow his dog to repeatedly attack and bite Secret Service and White House personnel."

"These shocking records raise fundamental questions about President Biden and the Secret Service," Fitton said. "This is a special sort of craziness and corruption where a president would allow his dog to repeatedly attack and bite Secret Service and White House personnel. And rather than protect its agents, the Secret Service tried to illegally hide documents about the abuse of its agents and officers by the Biden family."

Commander's arrival at the White House comes after the Bidens got rid of their prior dog, Major, who also behaved aggressively, including biting Secret Service and White House staff.

They eventually sent the dog, also a German shepherd, to live with friends in Delaware.
