Illinois Republican U.S. Senator Mark Kirk went against his own party yesterday, voting along with Senate Democrats in favor of four failed gun control measures in the wake of the Orlando shootings. Kirk voted along with fellow Illinois Senator Dick Durbin on each of the measures. Democrats forced votes on two amendments to expand background checks and prevent terror suspects from being able to buy guns. Republicans then added two competing measures. None of the measures hit the 60-vote threshold needed to move forward.
The news is likely to further damage Kirk’s support within the party. Kirk, who rescinded his endorsement of likely GOP Presidential nominee Donald Trump, is being challenged this November by Democratic U.S. Representative Tammy Duckworth.
