Sen. John Cornyn (R-Texas), the top Republican negotiator for the Senate’s newly unveiled gun control bill, has said he will not take part in a new round of gun control talks concerning proposals aimed at limiting access to certain rifles or expanding background checks.

The lawmaker was asked by reporters on July 12 whether Republicans would negotiate with Democrats on proposals that would limit the availability of some sporting rifles along with other gun control reforms, to which Cornyn simply replied, “No, we’re done,” according to The Hill.

The GOP lawmaker’s comments came shortly after President Joe Biden on July 11 urged Congress to pass laws implementing a new ban on civilian sporting rifles such as the AR-15, referring to them as “assault weapons,” following the mass shootings in Uvalde, Texas, and Highland Park, Illinois.

“We’re living in a country awash in weapons of war,” Biden said at the White House, seemingly in reference to civilian sporting rifles. “What is the rationale for these weapons outside war zones?”

“I am determined to ban these weapons again and high-capacity magazines that hold 30 rounds and let mass shooters fire hundreds of bullets in a matter of minutes,” he said. “I’m not going to stop until we do it.”
