ROCKIN' KC RED
President Joe Biden was so pumped to celebrate the Chiefs' Super Bowl win at the White House on Friday ... he actually donned one of Kansas City's red helmets!!
POTUS was gifted the headgear just minutes after he praised the team for winning its second straight championship ... and when Patrick Mahomes, Travis Kelce and the rest of the guys urged him to throw it on his dome -- he did just that!
The 81-year-old -- with help from head coach Andy Reid -- unbuckled the chinstraps .
