US President-elect Donald Trump walked out to The Undertaker's theme song at UFC 309. Trump appeared on The Undertaker's podcast during his election campaign. His real name is Mark Calaway.

The admiration appears to be mutual, however, as Trump previously entered a rally to The Undertaker's WWE theme song. Kane, meanwhile, has been a vocal supporter of Trump for a while now.
