Atlanta (CNN)Donald Trump is escalating his attacks on Sen. Marco Rubio with a special delivery for his rival: "Trump Ice Natural Spring Water."
Trump has previously trained his fire on Rubio, claiming he has the worst voting attendance record in the U.S. Senate and that he sweats a lot. But CNN learned that the Trump campaign sent a "care package" to Rubio's Washington campaign office that contained a 24-bottle case of "Trump Ice Natural Spring Water," with Trump's face on it, two "Make America Great Again" towels and bumper stickers and a note reading, "Since you're always sweating, we thought you could use some water. Enjoy!"
A Trump campaign aide said they added the towels "for him sweating," and described the overall gesture as a lighthearted prank.
