Texas Sen. Ted CruzRafael (Ted) Edward CruzDebbie Wasserman Schultz marks 10 years as breast cancer survivor Foreign agent registration is no magical shield against Russian propaganda Let Trump be Trump and he'll sail through 2020 MORE, a rising GOP star, downplayed speculation over a possible 2016 presidential bid, saying he was focused on his job in the Senate.

“We are having a national debate about which direction the country should go…and what I am doing now is trying to participate in that national debate,” Cruz told ABC News in an interview aired Sunday. “I’m not focused on the politics…the last office I was elected to was student council. So this has been a bit of a whirlwind.”

The Tea Party favorite spoke from Iowa, where he addressed a gathering of conservatives in the nation’s first caucus state. 

Cruz is also scheduled to headline a fundraiser for the New Hampshire GOP on Aug. 23, and has already visited early-primary state South Carolina, fueling speculation that he may be weighing a presidential bid. 

Cruz, though, was born in Canada, leading many to question his constitutional eligibility for the Oval Office.  

“My mother was born in Wilmington, Delaware. She’s a U.S. citizen, so I’m a U.S. citizen,” Cruz told ABC about those questions. 

“I’m not going to engage in a legal debate,” said Cruz. “The facts are clear.”

“I can tell you where I was born and who my parents were. And then as a legal matter, others can worry about that. I’m not going to engage,” he added.
