US President Joe Biden's two dogs have been sent back to his family home in Wilmington, Delaware after a "biting incident" with a White House security agent, AFP reported. 13-year-old Champ and three-year-old Major were sent back home after Champ was involved in the biting incident.
Major, whom Biden and his wife Jill adopted in November 2018 from an animal shelter, had been displaying aggressive behavior including jumping, barking and charging at White House staff and security, CNN reported, citing two anonymous sources.
The sources described a "biting incident" involving a member of the security services but did not specify if the person was injured. The episode was, however, seen as serious enough for both dogs, including 13-year-old Champ, to be returned to the Bidens' home in Wilmington last week.
Major is the first rescue dog to have lived in the White House, having moved in after Biden's inauguration in January.
Biden's predecessor Donald Trump did not have any pets at the White House.
It was not immediately clear when -- or if -- the dogs would be allowed to return.
First Lady Jill Biden said in an interview last month she had been focused on getting the dogs settled into their new home in Washington.
"They have to take the elevator, they're not used to that, and they have to go out on the South Lawn with lots of people watching them. So that's what I've been obsessed with, getting everybody settled and calm," she said on "The Kelly Clarkson Show."
