Donald Trump is again questioning Ted Cruz's eligibility to be president, saying the Texas senator came "straight out of the hills of Canada."

"You're registered as a Canadian citizen, he never knew he was a Canadian," Trump said while speaking to a crowd packed in a high school in Waterbury, Conn.


Trump said he's confident Cruz won't get the Republican presidential nomination, but believes Democrats would sue him if he were to ever become president.

"The first thing the Democrats are going to do is sue him on the basis that he’s not a naturalized citizen, he wasn’t born in the country," he said.

This isn't the first time Trump has picked away at Cruz's citizenship. Trump focused on Cruz's Canadian birth heavily in the days leading up to the Feb. 1 Iowa caucuses, at one point calling him "an anchor baby in Canada."

Cruz renounced his Canadian citizenship in 2014, and previously dismissed Trump's comments as "political noise."

“Look, as a legal matter the question is quite straightforward,” Cruz said in January. “It’s settled law that the child of a U.S. citizen born abroad is a natural-born citizen. People will continue to make political noise about it, but as a legal matter it’s quite straightforward.”

Trump's comments about Cruz today came during the first of two events in Connecticut, which is one of five states with primaries on Tuesday. There are 28 delegates at stake, and the few polls conducted there show Trump leading Cruz and Ohio Gov. John Kasich

Only a handful of polls have been conducted in the state — two last fall and two this month, according to RealClearPolitics polling data. Trump leads by more than 20 points, his average sitting at 49 percent, while Kasich and Cruz trail at 27 precent and 18 percent, respectively.
