Ted Cruz poked the bear.

During the Republican debate Thursday night, front-runner Donald Trump and Cruz -- who has moved into second place in most polls -- had a few sharp exchanges.

The fallout from the big one -- Cruz's attack on "New York values" -- dominated the campaign chatter Friday and is still bubbling. Said Cruz: "Everyone understands that the values in New York City are socially liberal or pro-abortion or pro-gay marriage-focus around money and the media."

Trump's response: "Very insulting." He then launched into a passionate defense of New York, including the city's response to 9/11.

Most called it one of Trump's better moments in the debates. (Cruz has since apologized -- not that Trump is buying it.)

Well, Trump is back Saturday morning with a volley of Tweets -- all directed at Cruz:

Ted Cruz was born in Canada and was a Canadian citizen until 15 months ago. Lawsuits have just been filed with more to follow. I told you so — Donald J. Trump (@realDonaldTrump) January 16, 2016

Ted Cruz said he "didn't know" that he was a Canadian Citizen. He also FORGOT to file his Goldman Sachs Million $ loan papers.Not believable — Donald J. Trump (@realDonaldTrump) January 16, 2016

Was there another loan that Ted Cruz FORGOT to file. Goldman Sachs owns him, he will do anything they demand. Not much of a reformer! — Donald J. Trump (@realDonaldTrump) January 16, 2016

The Ted Cruz wiseguy apology to the people of New York is a disgrace. Remember, his wife's employer, and his lender, is located there! — Donald J. Trump (@realDonaldTrump) January 16, 2016

Oh no, just reported that Ted Cruz didn't report another loan, this one from Citi. Wow, no wonder banks do so well in the U.S. Senate. — Donald J. Trump (@realDonaldTrump) January 16, 2016
