Sen. Marco Rubio (R-Fla.) discovered a link to Native American ancestors through an appearance on “Finding Your Roots,” according to the PBS show’s host.

Henry Louis Gates Jr. said in a preview clip for the show, airing Wednesday evening, that an ancestor on Rubio’s mother’s side was “pure Native American.”   

Gates also explained how the particular set of Native Americans Rubio is descended from migrated through the Yucatan Peninsula, a stretch of modern-day Mexico near Cuba, as early as 4,000 B.C.

“Talk about ancestral roots in Cuba … your family on your mother’s side has been there a long, long time,” Gates says in the video.

Rubio responds that he has visited ruins in the area, including Chichén Itzá, before remarking, “Who knew I was going back home?”

In his own tweet, Rubio hinted of more revelations on the episode, including a “famous distant relative.” 

“My Native American heritage was an amazing discovery. But you forgot one of the most surprising discoveries,my famous distant relative! I will have to break the bad news to him myself,” Rubio wrote.
