Sen. Marco Rubio said he apologized to presumptive Republican presidential nominee Donald Trump for remarks Rubio made about his hands and another appendage during a March campaign rally.
"You know what they say about men with small hands," Rubio said of Trump's hands during a campaign stop in March. "You can't trust them."
"I apologized to him for it," Rubio said on CNN Sunday. "I said, 'I'm sorry that I said that. That's not who I am, and I shouldn't have done it.'"
During Sunday's interview with CNN's Jake Tapper, Rubio conceded his attack on Trump "embarrassed" his family. He admitted he was desperate at the time.
"I mean, this guy is out there every day mocking people, saying horrible things about people, but if you respond to him and somehow, you're hitting him below the belt?" Rubio said. "That was my sense at the time."
"What I didn't realize at the time was it's not who I am. And if you're not being who you are, it doesn't come across well," he added.
During a Republican debate in March, Trump later said that Rubio was mistaken about the size of his hands — and the implication that resulted from it.
"Look at those hands, are they small hands?" Trump said during the debate. "And, he referred to my hands — 'if they're small, something else must be small.' I guarantee you there's no problem. I guarantee."
