There could be a “popular revolt,” if the Supreme Court blocks some kinds of gun control legislation, Sen. Chris Murphy (D-Conn.) said Sunday.

“If the Supreme Court eventually says that states or the Congress can’t pass universal background checks or can’t take these assault weapons off the streets, I think there’s going to be a popular revolt over that policy,” Murphy, an outspoken gun control advocate, said on NBC’s “Meet the Press.”

“A court that’s already pretty illegitimate, is going to be in full crisis mode,” Murphy added.
 
Murphy’s comments came after a federal judge ruled Wednesday that a federal law preventing the sale of guns to 18- to 20-year-olds was unconstitutional.
