'So snarky': Nikki Haley surrogate teaches Fox News host 'math' on Trump's age

New Hampshire Gov. Sununu (R), a surrogate for Republican presidential candidate Nikki Haley, reminded Fox News host Harris Faulkner that Donald Trump was nearing 80 years of age.

During an interview on Tuesday, Faulkner told Sununu that Haley continues to point to Trump's age as a reason not to vote for him.

"This is the guy that was blaming Nikki Haley for January 6," Sununu explained. "If he's off the teleprompter, this is not Donald Trump of 2016, guys."

"If he's off the teleprompter, he can barely keep a cogent thought," he added. "I've worked with him very closely. He's not the same guy. This is not Donald Trump... Yeah, look, this guy is nearly 80 years old."

Faulkner interrupted to defend Trump.

"He's 77," she remarked.

"That's nearly 80," Sununu shot back. "We'll do math later."

"You are so snarky," Faulkner complained.
