Professional wrestling legend Hulk Hogan told Republicans gathered in Milwaukee for the final night of their convention that former President Donald Trump is tougher than anyone he ever faced in the ring.

Hogan, whose real name is Terry Bollea has had a relationship with the party’s presidential nominee since the late 1980s, when Trump hosted Wrestlemania IV at his hotel and casino in Atlantic City, New Jersey. In the years that followed, Trump made numerous appearances on WWE programming.
