The reason Biden uses this bizarre virtual set for televised meetings—and not an actual room like East Room, Cabinet, Oval, Roosevelt, Sit Room, etc.—is because it allows him to read a script directly from a face-on monitor (& w/out teleprompter glass that can be seen on camera).
Trump used what for years? The wing of the White House for reporters? Yes but he never made it look like a White House /Oval Office set.
