Washington( CNN) He campaigned and won vowing to shake up Washington. Now, President Donald Trump is again breaking with tradition on a more personal thing: retaining a pet at the White House.

The illustrious tradition of continuing pets in the White House dates back to Thomas Jefferson, who maintained a mockingbird and a couple of carry cub during his presidency. Throughout the years, presidential pets became celebrities of sorts.

“It softens their image, it widens their appeal, ” Ed Lengel, chief historian at the White House Historical Association, told CNN. “They help create an atmosphere of the White House as a family, a lived-in place and not just a stiff museum, but a place where a family lives and plays and enjoys each other’s company.”
