Florida Gov. Ron DeSantis defended his call to ban pro-Palestinian groups from Florida state colleges Sunday, after one of his Republican presidential primary opponents, Vivek Ramaswamy, slammed the demand as “a shameful political ploy.”

“It’s unconstitutional. It’s utter hypocrisy for someone who railed against left-wing cancel culture,” Ramaswamy posted on X (formerly Twitter) Thursday, alleging that it violates students’ right to free speech.

DeSantis held firm Sunday.

“This is not cancel culture. This group, they themselves said, in the aftermath of the Hamas attack, that they don’t just stand in solidarity that they are part of this Hamas movement,” DeSantis said during an interview on NBC’s “Meet the Press.”
