Here's his response when asked about it later:Cruz, speaking to an enthusiastic crowd of roughly 650 Republicans at a Livingston County GOP dinner, told a series of jokes about Democrats, including the poorly timed jab at the vice president.
"You know, Vice President Joe Biden," he said as a few chuckles emerged from the crowd, setting up the joke for him.
"You know the nice thing. You don't need a punchline. I promise you it works. At the next party you're at, just walk up to someone and say, 'Vice President Joe Biden,' and just close your mouth. They will crack up laughing."
*******.Q: Could you talk about the vice president losing his son this week?
A: Heartbreaking and tragic, and our prayers are very much with Vice President Biden, with Jill. It's a tragedy no one should have to endure.
Q: Why'd you tell a joke about the vice president tonight?
A: Uh .... [walks away]
