Trump cites Biden, Obama, Beyonc and Elton John in defense of UFC 250 event [View all]
In response to a lawsuit seeking to halt what plaintiffs called a "deeply corrupt" plan to hold UFC cage fights at the White House this weekend, the Trump administration pointed to events hosted under prior administrations.
"No one raised a cavil at the Biden ice-rink or Elton John stage," the government said in its opposition filing.
It said that during Joe Biden's presidency, the White House "erected a 48 foot by 68 foot ice-skating rink on the South Lawn, complete with a 100-ton air cooled refrigeration system and pump, lighting system, and sound system," for an event that the filing said was "supported by the National Hockey League and Comcast."

It added that President Barack Obama "regularly put on exhibitions at the White House in partnership with private entities, including the South by South Lawn event; the concert entitled BET Presents: Love and Happiness: An Obama Celebration; as well as a Beyonce concert."

I think the big difference is unlike what Trump is doing these were private events. I believe Trump is charging donors to attend the UFC fight.
