A top gun-rights adviser to Sen. Ted Cruz’s presidential campaign claimed this weekend that President Obama’s nomination of Judge Merrick Garland to the Supreme Court is “his last-ditch effort” to “ruin the Second Amendment and destroy this country.”

Tim Macy, the chairman of the radical gun group Gun Owners of America and co-chair of Cruz’s “Second Amendment Coalition,” discussed the Supreme Court nomination in an interview Sunday with Mark Walters on “Armed America Radio.”

Macy said that Obama has “run up against the wall every time he’s tried” to “destroy the country” with gun restrictions, but that the Supreme Court vacancy is “his last-ditch effort before he leaves office to ruin the Second Amendment and destroy this country with Merrick Garland as his pick.”

Macy falsely claimed that Garland “supported the D.C. gun ban” — in fact, Garland, a federal appeals court judge in Washington, D.C., voted to rehear a case involving Washington’s handgun ban, which does not indicate at all where he stood on the merits of the case. In fact, Garland voted the same way as other judges on the court including Judge A. Raymond Randolph, whom Linda Greenhouse of the New York Times once called “one of the most outspoken and agenda-driven conservatives on the entire federal bench.”

“Clearly, if Garland got back on the court, the whole Heller decision, individual right to bear arms, would be put in severe jeopardy,” Macy claimed, “and you would have to imagine it would be gotten rid of as quick as the court could get another case up before them, they’d be looking for the case to bring up.”

Macy also brought up another case that gun groups have been using to attack Garland, in which Garland joined in a ruling that held that the FBI could temporarily store background check information from gun sales for audit purposes. Macy absurdly claimed that this shows that Garland “supports the ability of a president to illegally use executive power to advance liberal causes like taking guns away from honest citizens.”

These, he said, were all reasons to pressure Senate Majority Leader Mitch McConnell so that he “keeps that nomination on hold until the president’s gone and we have a new president.”
