As Donald Trump took the stage at the NRA Institute for Legislative Action Friday, MSNBC contributor and Business Insider editor Josh Barro took a shot at the length of the presumptive GOP nominee’s barrel.

The NRA is backing Trump because it’s not a gun rights group, it’s a group for people who are insecure about their penises. — Josh Barro (@jbarro) May 20, 2016

Just before Trump’s speech, Chris Cox, the NRA’s executive director, formerly endorsed Trump.

“We have to unite and we have to unite right now,” Cox told the crowd. “So on behalf of the thousands of patriots in this room and the five million NRA members across they country and the tens of millions who support us, I am officially announcing the NRA’s endorsement of Donald Trump.”
