Marco Rubio goes there with Trump: 'You know what they say about men with small hands ...'
At a Sunday rally in Roanoke, Virginia, the Florida senator got personal. After going after Trump's supposed spray tan and joking that Trump was going to "Make America Orange," Rubio zoomed in on the Republican frontrunner's hands.
"The other thing he says - he's always calling me 'Little Marco,'" Rubio said. "And I'll admit ... he's taller than me, he's like 6-2. Which is why I don't understand why his hands are the size of someone who's 5-2."
The crowd laughed and cheered.
"And you know what they say about men with small hands," Rubio continued, pausing for effect and grinning as the crowd reacted.
He then said: "You can't trust 'em!"
Rubio and Trump have been going after each other relentlessly with personal attacks since Rubio hit out at Trump at the Republican debate on Thursday night.
Trump is currently the frontrunner for the Republican nomination, with Rubio and Texas Sen. Ted Cruz trailing heading into Super Tuesday, when more than 10 states will vote.
Here's the video clip from the Rubio rally, which the Rubio campaign posted on its YouTube feed:
