Mark Cuban, the owner of the Dallas Mavericks, was invited by the Clinton campaign to sit in the front row at Monday night’s debate.

“Just got a front row seat to watch @HillaryClinton overwhelm @realDonaldTrump at the “Humbling at Hofstra” on Monday,” Cuban tweeted. “It Is On!”

A Clinton aide later confirmed that Cuban was, in fact, invited by the Clinton campaign.

“He has the best seat we have access to,” the aide said.

Cuban has tried to publicly shame Trump throughout the 2016 campaign, regularly slamming the Republican nominee for not releasing his taxes. The attacks have been particularly effective, given Cuban’s status as a fellow billionaire and his public persona as a similarly brash businessman.
