Sen. Ted Cruz, R-Texas, noted on Sunday that Jon Stewart was a “very funny guy” even though the popular comedian called him a “dirty syrup guzzler.”

(Stewart was referring to Cruz’s birth in Canada – although Cruz was born an American citizen because of his mother.)

Cruz explained to ABC’s reporter Jonathan Karl that he responded to the joke by sending Stewart a letter and a bottle of Texas syrup.

“I’ll confess I wasn’t sure what that was, but I will tell you in response to that, I did send Jon Stewart a letter saying that I rarely guzzled syrup,” he said. “But any time I did, it was Texas syrup. And sent a bottle of it, and invited him to syrup festival in the state of Texas.”

Cruz added that he got a “very nice phone call” back.
