Cavaliers owner Dan Gilbert was a guest on CNBC’s show Squawk Box on Friday and was asked if he talked to LeBron James about calling President Donald Trump a “bum” on Twitter.

James posted that “bum” tweet after Trump withdrew Steph Curry’s invitation to the White House and after the president called NFL players who protest during the anthem “sons of b—.” The Cavs star then expanded on his comments in a video, saying Trump is “now using sports as the platform to try to divide us.”

Gilbert said that he and James “didn’t have any specific discussions” about the tweet, and then he went on to share that he received “vile, disgusting, racist,” voicemails afterwards, though he also made a point to say that there is “rhetoric … and emotions on both sides of this thing.”

“There’s an element of racism that I didn’t even know existed in this country,” Gilbert said on CNBC. “I didn’t even tell LeBron this, now he’s gonna know. Some of the most disgusting things I’ve ever heard people say, you could hear it in their voice.”

U bum @StephenCurry30 already said he ain't going! So therefore ain't no invite. Going to White House was a great honor until you showed up! — LeBron James (@KingJames) September 23, 2017

James and Gilbert have had very different reactions to Trump since he became president. James has openly criticized the president other times in addition to calling him a “bum,” while the company Gilbert founded, Quicken Loans, gave $750,000 to Trump’s inauguration.

And Gilbert was at the White House the same time that the Cubs were there to celebrate their championship in June.

Earlier this week, Gilbert released a statement before appearing at a STEM education event with Trump’s daughter and advisor, Ivanka Trump. Here’s part of it, per Cleveland.com:
