Kanye West might be buddies with President-elect Donald Trump, but he won’t be performing at Friday’s inauguration.

That’s because he wasn’t invited to take the stage.

Tom Barrack, chairman of Trump’s Presidential Inauguration Committee, told CNN that though West and Trump are friendly, West is not “traditionally American” enough for the event.

“He’s been great, he considers himself a friend of the president-elect, but it’s not the venue,” Barrack said. “It’s going to be typically and traditionally American, and Kanye is a great guy — we just haven’t asked him to perform.”

The comment had Twitter users speculating what Barrack meant by “traditionally American.” Some pointed out that Michael Flatley of Irish musical “Lord of the Dance” is performing.

Actor Jesse Williams pointed out that Trump’s grandparents were not born in the U.S. (Trump’s father’s parents were from Germany and his mother was born in Scotland), and said, “Kanye’s ‘more American’ [than] Trump.” He also incorrectly said that Michael Flatley is an Irish national (Flatley was born in the U.S.).

-Irish nat'l Michael Flatley is though 🤣. -NONE of Trump's grandparents were born in the U.S. -Kanye's "more American" then Trump. https://t.co/qDZfPZFIjp — jesse Williams. (@iJesseWilliams) January 19, 2017

Others were more blatant in their criticism. One Twitter user wrote, “Sorry, Kanye! Guess you made that trip to the golden tower for nothing! Your music’s just too black for Trump’s ‘traditional’ America.”
