Donald Trump Goes on Apology Tour

The Republican frontrunner admits that he misspoke on abortion comments and that

"Was this my best week? I guess not," he admitted on Fox News Sunday.

But for the businessman who rarely admits a mistake, today he admitted two.

"Yes. I would have rather answered it in a different manner," he said on "Fox News Sunday" of his initial comments.

On Sunday, however, Trump offered a mea culpa, of sorts.

"If I had it to do again, I probably wouldn't have sent it. I didn't think it was particularly bad, but I probably wouldn't have sent it,” he said.

Since then, the two have sparred back and forth, Trump threatening to "spill the beans" on Heidi Cruz, days before a National Enquirer report suggested that Cruz had been unfaithful to his wife. Cruz responded by calling Trump "a sniveling coward" and warning Trump to leave his wife "the hell alone."
