It said that Trump’s campaign sent Rubio a 24-bottle case of “Trump Ice Natural Spring Water” with the outspoken billionaire’s face on it.

It also mailed the Florida lawmaker two towels and several bumper stickers boasting Trump’s “Make America Great Again” slogan.

“Since you’re always sweating, we thought you could use some water,” the Trump campaign reportedly wrote in a letter to Rubio’s staff. "Enjoy!”

CNN reported on Monday that Trump’s brand of bottled water comes in 16.9 oz. containers made in Willington, Conn. The real estate mogul is fond of providing them at his multiple properties all over the world, it continued.

“Water for the body and soul,” Trump’s water bottles are reportedly labeled. "This is water the way it was meant to be.”

Monday’s gag is the latest in an increasingly personal public battle between Rubio and the GOP front-runner.

Trump has repeatedly taunted Rubio for his GOP State of the Union response two years ago. Rubio inspired widespread derision for awkwardly gulping a water bottle on-air during the high-profile address.

Trump has since argued that the Florida lawmaker is too green for the White House given his youth and immaturity in office.

“He’s got the worst voting record in the United States Senate,” he said of Rubio last month. "He’s never there, meaning he doesn’t work or he’s too lazy to go back and vote.”

“He shouldn’t even be running in this race, as far as I’m concerned,” Trump added. “He’s a kid.”

Rubio has countered that Trump can't handle criticism and has created a “freak show” on the 2016 campaign trail.

Trump leads the race for next year’s Republican presidential coronation with 22.8 percent, according to the latest RealClearPolitics average of samplings.

Rubio, meanwhile, ranks fourth out of 15 candidates with 9.5 percent voter support of his own.
