WASHINGTON - On Wednesday, as President Joe Biden began his duties as commander in chief, several touching photographs — including a photo with his late son Beau Biden — were featured prominently in the Oval Office behind the Resolute Desk.With Beau's photo behind him, Biden began his term signing 17 executive orders on Wednesday, including a mask mandate on federal property and the rejoining of the Paris climate agreement — and it is likely that Beau's legacy will continue to be an influence on the president's decisions over the next four years.A sculpted bust of Cesar Chavez oversees a collection of personal framed photos on a table seen during an early preview of the redesigned Oval Office awaiting President Joseph Biden at the White.
