Alabama Sen. Jeff Sessions said the Second Amendment right to keep and bear arms would become nearly extinct if Hillary Clinton wins the presidency.

Sessions told "Fox News Sunday" that "Hillary Clinton is the most anti-Second Amendment president perhaps we've ever had" and cautioned voters to consider the damage to gun rights her presidency would cause.

The senator said Clinton would pick a liberal Supreme Court Justice to fill the court's vacancy, with potentially disastrous ramifications.

"And what that means is, it's no longer a personal right to have a gun, but every city, county, and state can completely ban firearms in America," Sessions told Fox News. "This would be the greatest reduction of Second Amendment rights since the founding of the republic."

Sessions is an ardent supporter of Donald Trump, who earned the endorsement of the National Rifle Association late last week.
