Republican Sen. Marco Rubio of Florida had harsh words when he was running against presumptive Republican nominee Donald Trump in the GOP primary, going so far as calling him a "lunatic" and a "con artist."
But now Rubio said he'd be “honored” to help Trump become president.
"Look, my policy differences with Donald Trump -- I spent 11 months talking about them. So I think they're well understood," Rubio told CNN's "State of the Union." "That said ... I don't want Hillary Clinton to be president. If there's something I can do to help that from happening, and it's helpful to the cause, I'd most certainly be honored to be considered for that."
Before Rubio dropped out of the GOP primary, he had a much different way of describing his policy differences with Trump.
"I would prefer not to get into a fight with other Republicans. But I would much more prefer not to turn over the party to a con artist like Donald Trump,” Rubio said after a February GOP debate, reported CNN.
Rubio once even compared Trump to North Korean leader Kim Jong Un.
"There is a lunatic in North Korea with nuclear weapons. And some would say a lunatic trying to get ahold of nuclear weapons in America,” Rubio said in February, according to The Week.
And Trump didn't sit back, often referring to Rubio as “Little Marco” and blasting his debate performances.
"Lightweight Marco Rubio was working hard last night. The problem is, he is a choker, and once a choker, always a chocker! Mr. Meltdown,” Trump tweeted after a GOP debate in February.
But that was in the past. Rubio now says he is willing to speak at the Republican convention, where Trump is expected to get the nomination, and help the GOP win the White House.
And after previously indicating he might retire from politics, 44-year-old Rubio now says he might not.
"I can tell you I enjoy public service. If there's an opportunity to serve again in a way that I feel passionate about, I'll most certainly think I would explore it," Rubio said. "But I don't know where I'm going to be in two years. I don't know what my life will look like then."
