GOP frontrunner Donald Trump reportedly said he might file a lawsuit over fellow GOP presidential candidate Sen. Ted Cruz’s (R-TX) eligibility to be President of the United States.

“I’ve said Ted has a lot of problems — number one, Canada. He could run for the Prime Minister of Canada and I wouldn’t even complain because he was born in Canada,” Trump said during a campaign event in Iowa. “The Democrats are going to sue if he ever got the nomination within two days. There have already been two lawsuits filed, but they don’t have standing. I have standing to sue. Can you imagine if I did it? Should I do it just for fun?”

Trump said he was confident he would defeat Cruz and win the Republican nomination, so he doesn’t need to file the lawsuit.

“It’s probably why I want to save the legal fees,” Trump touted. “If I thought it was going to matter, maybe I would do it, maybe I wouldn’t.”

Trump ignited the debate over whether or not Cruz is a “natural born” citizen and able to be president because he was born in Canada; however, his mother was a U.S. citizen.
