A Republican senator called Monday for his colleagues to vote for his “no fly, no buy” legislation as the Democratic alternative would potentially violate law-abiding citizens’ Second Amendment rights and “would not be as tough on the terrorist as mine would be.”

Sen. John Cornyn, R-Texas, said on the Senate floor he was concerned that the amendment proposed by Sen. Dianne Feinstein, D-Calif., would violate the Second Amendment rights of law-abiding citizens by referring to a “secret” watch list maintained by the government to deny the ability to buy a firearm “without due process of law.”
