“I think he did the right thing by apologizing. He was trying to be funny, and it didn’t work,” Graham said Friday in an interview with Yahoo’s Katie Couric.

"He called our office and I said, ‘Mark, don’t worry about it.’ I know Mark. He is a good guy.”

Kirk made the comment during a committee hearing on Thursday.

“He's a bro with no ho," Kirk said, using a phrase that includes a derogatory term for a woman. 

“That's what we'd say on the South Side.”

Kirk’s spokeswoman told The Hill that he was “joking with his colleague and immediately apologized to anyone offended by his remark.”

But critics quickly pounced, with the Democratic Senatorial Campaign Committee immediately attacking Kirk with emails and press releases.

Kirk is one of the most vulnerable senators in the upcoming election cycle and both of his Democratic challengers are women. Rep.

Graham, who is seeking to be the first bachelor president in more than 100 years, told Couric that no one in early primary states seems to care about his marital status

“Here’s the question for the country: Can you be single and still be president? Is it a job for married people only?  Is there a sign on the White House, ‘Single people may not apply?’ I don’t know, I haven’t seen it,” he said.

“I’m going to run being me, and I like me. If nobody else likes me, I like me.”

While he admitted that he had “come close once” to getting married, he wouldn’t elaborate.

“We’ll have to talk to Dr. Phil about that,” he said.

“Can you contribute to society being single? I think so.”
