Cruz apologizes to Carson over Iowa; Carson not impressed

It didn't take long for the controversy over Ted Cruz, Ben Carson and the Iowa caucuses to come up at Saturday night's debate in New Hampshire.

To quickly recap, on the night of the caucuses, Cruz's staff disseminated an incorrect statement that Carson was likely to drop out of the race. Cruz later apologized that his staff never corrected the information. He did so again during the debate.

Carson, when given the opportunity to address the issue Saturday, said he wanted to follow Ronald Reagan's 11th commandment on not attacking fellow Republicans.

“I’m not going to use this opportunity to savage the reputation of Sen. Cruz," Carson said, then said he was "very disappointed that members of his team thought so little of me" to spread the erroneous information.

He said the campaign's actions were an example of "Washington ethics," which he defined as “if it’s legal, you do what you need to do in order to win."

Cruz again apologized, while offering a timeline for what transpired.

“Ben, I’m sorry," Cruz said to the retired neurosurgeon.

“I knew nothing about this," he added, saying he wished "that our campaign staff had forwarded" a corrected report.
