SAN ANTONIO -

Sen. Ted Cruz (R-TX) spent Tuesday in Houston talking about the economy and how to defund the Affordable Care Act but most questions for him centered around last weekend's news that Cruz holds dual citizenship in the U.S. and Canada.

Cruz was born in Calgary, which automatically gave him Canadian citizenship but was also granted U.S. citizenship thanks to his mother, Eleanor.

Cruz said Tuesday that he plans to renounce his Canadian citizenship, which he claimed he didn't think he had a right to.

"When I was a kid my mother told me if I ever wanted to I could affirmatively choose Canadian citizenship since I was born there, but I got a U.S. passport, never did anything to claim it, lived my whole life here, and so I thought that was the end of it," said Cruz.

"I'm sorry I can't help but laugh," said Dr. Mansour El-Khikia, political science chair at the University of Texas at San Antonio. "It's just such a lame excuse. So silly! What do you mean he didn't know he was a dual citizen?! How is that possible?"

While Cruz was not a loud voice in the birther movement against President Obama, El-Khikia said the whole issue reeks of irony.

"Here's a guy who was born in Hawaii and they're challenging his birthright and this guy was born in Canada and he's saying, 'Well it's ok if I'm President,' said El-Khikia. "The irony of politics and the hypocrisy of politics is very evident and I think Senator Cruz brings it to the forefront."

El-Khikia believes that Cruz's decision to respond immediately could play in his favor if he does make a serious push at a Presidential bid.

"He realized that if he didn't say it, come out with it now, it would come out in the future to haunt him," said El-Khikia.

Cruz will speak in Kerrville on Wednesday, then Austin and Waco on Thursday before heading to New Hampshire on Friday.
