Joseph McBride, an attorney for several Jan. 6 defendants who was a key figure in Carlson’s “Patriot Purge” series on the Fox Nation streaming service, told Fox News viewers that #RedFace45 had his face painted “MAGA red” but he was only in disguise as a Trump supporter.

“He is clearly a law enforcement officer,” McBride told Carlson’s viewers of #RedFace45, saying the man was part of a government entrapment scheme in which Trump supporters were handed weapons by government agents “for reasons that we cannot comprehend.”

But the man is no fed. He is mainly known to St. Louis Cardinals fans as “Rally Runner,” HuffPost has learned, and he sprints around the outside of Busch Stadium during home games. Based on the man’s Facebook posts, he appears to have a fairly difficult life and has a tenuous relationship with reality. And he’s a huge Tucker Carlson fan.

“Rally Runner” is somewhat of a local celebrity in St. Louis. A photo of him was featured in The St. Louis Post-Dispatch in October 2013, when the Cardinals reached the World Series. The man, who did not provide a name, told the paper his running “strengthens the spirit for the Cardinals to get the energy to win.”
