On Tuesday, former Breitbart chief executive and future chief strategist to the President, Steve Bannon, had a surreptitious meeting with Trump nemesis, billionaire Mark Cuban. The two met at the upper-class King Cole Bar at the St. Regis Hotel in New York City, according to a report by celebrity media outlet TMZ.

The meeting comes as Bannon fields criticism regarding his affinity for the controversial, ethno-nationalist alt-right movement.

It’s unclear what the two men talked about, but the meeting was quite strange considering the fact that Cuban fervently campaigned for Trump’s rival Hillary Clinton. “I’d rather lose every penny than have Trump as president,” the Dallas Mavericks owner said before Clinton’s humiliating loss on November 8th.

However, Cuban has adopted a more genteel approach to Trump since election day, telling Americans to give the president-elect “a chance” before casting premature judgment.

TMZ has suggested that Bannon and Cuban met to discuss politics. While the two men have interacted before, discussing mostly business, Tuesday’s low-key and unpublicized meeting may signal a thawing in Cuban’s relationship with fellow-billionaire and soon-to-be president, Donald Trump.

Regardless of whether the two buried the hatchet or not, the Trump team have made efforts to reach out to disaffected political opponents, including Republicans who had been resistant to a Trump presidency.
