Sen. Marco Rubio is maintaining a blistering campaign pace, concluding a fourth rally in the state of Virginia last night in Salem, Virginia, in front of a huge crowd of supporters.

But he wasn’t finished insulting Donald Trump, mocking the size of his hands — and alluding to the size of his manhood.

“He’s always calling me ‘Little Marco’ … and I’ll admit he’s taller than me, he’s 6’2″ which is why I don’t understand why he has hands the size of someone who’s 5’2″. Have you seen his hands? You know what they say about men with small hands,” Rubio said pausing for dramatic effect before adding, “You can’t trust them. You can’t trust them. You can’t trust them. All right? You can’t trust them.“

Rubio’s voice had gone hoarse after a big day of campaigning, but he earnestly continued. He also again mocked Trump’s spray tan.

“He doesn’t sweat because his pours are clogged from the spray tan that he uses,” he said. “Donald is not going to make America great, he is going to make America orange!”

In Virginia Beach, Rubio taunted Trump for vowing to end job outsourcing in America.

“He says he’s fighting to bring jobs from China, well why don’t you start by bringing those factories that make your suits and your ties with a Donald Trump label on it?” he asked. “Those jobs are made in China.”

He warned that Trump was dangerous to the conservative movement, who would lose to Hillary Clinton if nominated for president.

“I’m telling you, if we nominate Donald Trump, who today is the frontrunner, we will lose this election to Hillary Clinton,” he said.

In Purcellville, Virginia, Rubio brought up a controversial interview Trump had earlier in the day on CNN.

“He was asked this morning two times, ‘Will you repudiate and condemn the Ku Klux Klan?’ and he refused to do that as well,” Rubio said. “We cannot be a party that nominates someone who refuses to condemn white supremacists and the Ku Klux Klan.”

He also mocked a protestor who disrupted his rally with a sign that said “Marco Rubio Empty Suit.”

“Well at least this suit isn’t made in China. It’s not a Trump suit,” he said, as supporters tore at the sign and chanted, “Marco! Marco! Marco!”

On the Sunday morning shows, Rubio ridiculed Donald Trump’s history of business failures. He continued the attack that he began in the debate on “Trump University,” reminding voters of the “con job” that he was playing on the Republican party.

“This is part of the clown act. This is what happens when someone is caught, like Donald Trump has been, as a con artist,” he said on Fox News Sunday.

On Saturday, Rubio mocked Trump’s face during a campaign rally in Georgia.

“[It’s] amazing to me that the guy with the worst spray tan in America is attacking me for putting on makeup,” Rubio said. “Donald Trump likes to sue people, he should sue whoever did that to his face.”

He also alluded that Trump was a dangerous dictator, unfit for the White House.

“There is a lunatic in North Korea trying to get a nuclear weapon and a lunatic trying to get ahold of nuclear weapons in America,” he said.

Although Rubio appeared to enjoy the attacks, he apologized to some audiences for stooping to Trump’s level.

“I’ve used strong words and my parents didn’t raise me that way, but I’ve used strong words because I feel that passionately about it,” Rubio said, during the Yellowhammer News Presidential Forum in Homewood, Alabama.
