Three Republican senators told Senate Majority Leader Harry Reid today they will filibuster any gun legislation that infringes on Second Amendment rights.

Reid said last week the Senate will debate on gun legislation that expands background checks and stiffer penalties for trafficking after Easter recess.

“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, which the Washington Post linked to.

The trio did not include specifics in their three-paragraph letter, but said any attempt to pass such legislation will meet with opposition.

“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,” the senators wrote. “We will oppose the motion to proceed to any legislation that will serve as a vehicle for any additional gun restrictions.”

A spokesman from Reid’s office told the Huffington Post, “While this threat is entirely unsurprising, it’s outrageous that these senators are unwilling to even engage in a debate over gun violence in America. No matter your opinion on this issue, we should all be able to agree with President Obama when he said that the children and teachers of Newtown, along with all other Americans who have been victims of gun violence, at least deserve a vote.”

Vice President Joe Biden said last week that none of the proposals the White House has proposed — including an assault weapon ban— infringes on anyone’s Constitutional rights.

“There is not one single thing— not one, not one single thing— being proposed that infringes on anyone’s Second Amendment rights,” he said.
