The National Republican Senatorial Committee (NRSC) will launch three separate advertisements going after three Democratic senators for voting with President Joe Biden’s administration and Democrats in Congress over a Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) pistol brace rule that they say affects veterans.

The NRSC’s latest ad campaign, first obtained by the Daily Caller, slams Montana Sen. Jon Tester, West Virginia Sen. Joe Manchin, and Ohio Sen. Sherrod Brown for voting with Biden to support a new ATF pistol brace rule that Republicans argue would make it harder for wounded veterans to safely and effectively exercise their right to keep and bear arms.

GOP lawmakers and veteran groups have tried to fight the ATF after they enacted a rule that would make pistol stabilizing braces illegal for anyone without a certain license. The rule would make gun owners face the possibility of being charged with a felony if they do not register their firearms with the stabilizing braces which GOP lawmakers say would directly impact wounded veterans.
