State Sen. Leah Vukmir (R-Brookfield) picked up a key endorsement in her race for the U.S. Senate. Vukmir announced on the Jay Weber show on WISN-AM that she received the endorsement of the National Rifle Association (NRA).

“I’m proud to announce today that I’m being endorsed by the National Rifle Association,” Vukmir told Weber. “I’m incredibly proud of this. It is a big deal. The NRA doesn’t always get involved in senate primaries but clearly they see a distinction between me and my primary opponent and today they are announcing they’re endorsing me in this race giving me an A+ rating for my work on the 2nd Amendment.”

Weber noted that it’s rare for the NRA to get involved in Republican primaries and asked Vukmir why she thinks she received the organization’s endorsement.

“They clearly see the distinction and I believe it’s because I have a proven track record,” Vukmir said. “They know my track record as standing up for the 2nd Amendment, standing up for the issues that matter to them. And people know they can count on me to take on the tough battles in D.C. because I’ve done it here in Wisconsin.”

Vukmir is facing Kevin Nicholson in the Republican primary on August 14. The winner of the primary will face Sen. Tammy Baldwin (D-WI).

On his website, Nicholson claims he supports and will protect the rights of gun owners.

“As a Marine veteran and a gun owner, Kevin strongly supports the 2nd Amendment,” the website reads. “Kevin will protect the rights of Wisconsin citizens to own and carry firearms.”

However, when Nicholson was president of the College Democrats, he wrote a letter to Hollywood actress Rosie O’Donnell inviting her to speak on gun control. “There is no single issue more important to our membership then {sic} the elimination of gun violence in America, particularly our schools,” the letter said. “The members of CDA are committed to electing a Congress and a President that support the common sense gun control measures which were demonstrated so fervently at the Million Mom March, and by you every day.”

Nicholson’s campaign did not immediately respond to a request for a statement concerning the endorsement.

In the endorsement letter, NRA Chairman Chris Cox praised Vukmir for her work in the state legislature.

“We are especially thankful for your vote to make Wisconsin a ‘shall issue’ state, as well as your co-authorship of Constitutional Carry legislation,” Cox wrote. “We also applaud your support for Concealed Carry Reciprocity legislation, which would ensure that nearly 20 million law-abiding Americans who can carry a concealed firearm in their home state are able to do so in any other state that does not prohibit concealed carry.”

Vukmir also touted her legislative accomplishments in the interview with Weber. “I’ve worked hard to increase self-defense protections for Wisconsinites through the various pieces of legislation we’ve been able to advance since we’ve been in the majority: castle doctrine, concealed carry, repealing the 48 hour waiting period,” Vukmir said. “And I might add that some of those bills were bipartisan. Concealed carry, for example, was a bipartisan bill, if you’ll recall.”
