Donald Trump on Friday received his first major endorsement from a high-profile celebrity.

Former NBA superstar Dennis Rodman tweeted out his support for Trump's candidacy, citing the real-estate mogul's business experience.

Trump quickly thanked Rodman for his support.

The reality television star has been lacking in serious endorsements, which campaign strategists point out are a key to winning the nomination. At this point, the only major public figures to endorse Trump are Rodman and Stephen Stepanek, a state representative in New Hampshire.

Rodman has made political headlines before. In 2013, Rodman traveled to North Korea to meet with dictator Kim Jong Un, who impressed the former NBA star.

“To see a guy like that , this 5-foot-2 or 5-foot-1 guy, have that much power, in a country like that, and see people get emotional, crying, 20,000 of them clapping, it was so surreal,” Rodman said, according to The Washington Post. “It blew my mind.”

Trump's relationship with Rodman wasn't always this good. Last year, Trump tweeted that he was "glad" that he fired Rodman from The Apprentice after the former NBA star failed to spell Trump's wife's name correctly.
