Donald Trump Is 'Not Sure' Where Ted Cruz Was Born (VIDEO)

When it comes to birth certificates, Donald Trump's concerns surrounding President Barack Obama's document have historically been high.

Trump faced a similar question Sunday on Sen. Ted Cruz (R-Texas). In an interview with ABC's "This Week," Trump was asked by Jonathan Karl whether Cruz's birth in Canada makes him eligible to be president of the United States.

"Well, if he was born in Canada, perhaps not," Trump said. "I'm not sure where he was born."

"Oh, he's definitely born in Canada," Karl replied.

"Ok, well then you'll have to ask him that question, but perhaps not," Trump shot back.

Trump's comments came immediately after he revived the same debate about Obama on Sunday.

"Was there a birth certificate?," Trump asked Karl. "You tell me. Some people say that was not his birth certificate. I’m saying I don’t know. Nobody knows."

Back in April 2011, Obama released a version of his long-form birth certificate, criticizing the press for "silliness" over the issue.

"I know that there is going to be a segment of people for which no matter what we put out, this issue will not be put to rest," Obama said. "But I am speaking for the vast majority of the American people as well as for the press. We do not have time for this kind of silliness. We have better stuff to do. I have got better stuff to do. We have got big problems to solve."
