A trio of Republican senators on Tuesday warned Senate Majority Leader Harry ReidHarry ReidOvernight Finance: Trump threatens NAFTA withdrawal | Senate poised for crucial Puerto Rico vote | Ryan calls for UK trade deal | Senate Dems block Zika funding deal The Trail 2016: 11 hours, 800 pages, 0 changed minds Senate faces critical vote on Puerto Rico MORE (D-Nev.) they plan to filibuster any attempts at bringing new gun control legislation to the floor of the Senate.
The move comes just days after Reid announced plans to push forward on a gun control bill which would expand background checks and penalties on straw purchasers.
"We, the undersigned, intend to oppose any legislation that infringe on the American people's constitutional right to bear arms, or on their ability to exercise this right without being subjected to government surveillance," the senators wrote in the letter, a copy of which was obtained by Fox News.
The senators pledge in the three-paragraph letter they "will oppose the motion to proceed to any legislation that will serve as a vehicle for any additional gun restrictions."
"The Second Amendment to the Constitution protects citizens' right to self-defense. It speaks to history's lesson that government cannot be in all places at all times, and history's warning about the oppression of a government that tries," they wrote.
President Obama and congressional Democrats have been pushing for new gun controls in the wake of the Newtown, Conn. elementary school shooting late last year that left 20 schoolchildren and six educators dead.
The White House initially proposed that lawmakers consider a renewed assault weapons ban and limits on magazine capacities as part of new gun-control measures. But Reid proceeded without those controversial provisions, acknowledging they did not have enough votes to pass the Senate. The provisions will be offered as an amendment to the legislation.
The White House also said Monday that President Obama would stump in coming weeks in hopes of intensifying pressure on Congress to pass the gun control bill.
