I tend to doubt it. Even on a president's salary, he wouldn't be able to afford weekly parties for the Dems with $100/lb. wagyu beef. WH meals are likely free for the "First Family" - it's a 'perk' we get to pay for . . . . . . like AF1.
The president pays for his own and the first family’s personal food.
