币界网报道：The Senate parliamentarian has blocked a Republican attempt to attach gun deregulation measures to a must-pass defense bill, dealing a setback to GOP efforts to loosen firearm restrictions. The proposed amendments, championed by Senator John Cornyn (R-TX), sought to roll back regulations on gun silencers and allow concealed carry permits to be recognized across state lines. Democrats argued these provisions were unrelated to the National Defense Authorization Act (NDAA) and violated Senate rules requiring amendments to be germane to the underlying legislation. Parliamentarian Elizabeth MacDonough agreed, ruling the measures out of order. Senate Majority Leader Chuck Schumer (D-NY) praised the decision, calling it "a victory for common sense and public safety." The move comes amid heightened national debate over gun control following recent mass shootings. Republicans expressed disappointment but vowed to pursue the measures through other legislative avenues. The NDAA, which authorizes $886 billion in military spending, is expected to pass without the controversial gun provisions. Advocacy groups on both sides of the issue are now shifting focus to upcoming standalone gun legislation battles in Congress.
