President Joe Biden and first lady Jill Biden made two important additions to the White House over the weekend, their dogs. German shepherds Champ and Major moved in on Sunday. The first lady announced the big development on Twitter. Champ and Major have joined us in the White House! she wrote on Monday. The two have quickly made their presence known. When reporters gathered Monday to watch the new president sign an executive order, Champ and Major could be heard barking outside. Photographers took videos and pictures of Champ and Major playing on the South Lawn of the White House. Their arrival marks a return of the tradition of first pets. Many past presidents have brought their dogs or other popular pets to the White House. Donald Trump was the first president in many years to not have a pet during his time in office.
