Despite their previous disagreements, Senator Marco Rubio (R-FL) said Thursday that he will attend the Republican convention and, if asked, speak on the behalf of presumptive nominee Donald Trump.

“My sense is that I will go to the convention,” Rubio told CNN, in comments quoted by The Blaze. “I don’t know if I will have a role in the convention.”

Asked if he would deliver a speech on behalf of Trump, who has passed the number of delegates needed to secure the Republican presidential nomination, Rubio said: “I’d certainly. Yeah. I want to be helpful. I don’t want to be harmful because I don’t want Hillary Clinton to be president.”

Rubio’s comments represent a sharp change in rhetoric from when he was on the campaign trail, noted The Blaze.

When the Florida senator was running against Trump for the nomination, he said he would “get in my pickup truck and drive around the country” if it’s what it would take to stop Trump from being elected president.

At one rally, he suggested Trump was a “lunatic” who could not be trusted with nuclear weapons. At others, he called him a “con man” who had tricked conservatives into thinking he was one of them.

In one televised debate, Rubio accused Trump of showing an "anti-Israel" stance, due to Trump's earlier comments that he would be "neutral" and "unpredictable" in pressing peace talks on Israel and the Palestinian Authority (PA).

Rubio, who dropped out of the presidential race soon after losing to Trump in his own state of Florida, is only one of the many Republicans who have warmed to Trump in recent weeks, noted The Blaze.

Rep. Darrell Issa (R-CA), who supported Rubio for president, said he will back Trump earlier this month. Others, including Senate Majority Leader Mitch McConnell (R-KY) former Louisiana Gov. Bobby Jindal and Sen. Rand Paul (R-KY), have also expressed support for the presumptive nominee.

Despite his change of heart with regards to Trump, Rubio recently made clear he would not consider being the billionaire’s running mate.
