Colby Covington Visits White House 'Unlike The Filth-a-delphia Eagles'

Colby Covington promised he'd make it out to see Donald Trump "unlike the Filth-a-delphia Eagles" after winning his championship fight last month ... and he finally made good on that on Wednesday.

"Like Donald Trump always says: Promises made. Promises kept," Covington said of the visit.

"Pleasure to finally meet you Mr. President. Thank you for always putting America first!"

Remember ... the UFC superstar beat up on Rafael dos Anjos at UFC 225 -- and took a shot at the NFL's Super Bowl champs while promising a White House visit afterward.

"I told everybody I was going to make the welterweight division great again, and now I’m going to celebrate how a real American should celebrate winning a world a title," Covington said.

"And that’s going to the White House to see Mr. Donald Trump and put this on his desk, unlike the Filth-a-delphia Eagles disrespecting our flag and kneeling for the national anthem.”
