TheBlaze host Glenn Beck, surrogate for Republican presidential candidate Sen. Ted Cruz (R-TX), praised Cruz’s rival Sen. Marco Rubio (R-FL) on Twitter.

“Rubio is killing it,” Beck tweeted during CNN’s Republican presidential debate in Houston, Texas.

The debate is the final one before Super Tuesday. Beck endorsed Cruz in January, calling him the “next George Washington.” Since his endorsement, Beck has acted as a surrogate for Cruz, campaigning with him in early states.
