Watch: Salon Shooting Victim's Sister Speaks at Gun-Control Rally

About 150 gun-control supporters, including the sister of a woman who died in Seal Beach's infamous salon shooting, gathered outside a gated Irvine neighborhood Thursday, waving signs and flags in an attempt to make their presence known to some rather big political names partying on the other side of the security checkpoint.

The biggest of those names was House Speaker John Boehner (R-Ohio), the main draw at a fundraising dinner in the home of private equity fund CEO David Horowitz and his wife, Michelle. Boehner also brought along fellow  congressmen Dana Rohrabacher (R-Huntington Beach), Ed Royce (R-Fullerton) and John Campbell (R-Irvine).

The outside rally was sponsored by three Orange County gun violence prevention groups -- Moms Demand Action, the Brady Campaign to End Gun Violence and South County Citizens Against Gun Violence. All were united in a single message -- wanting Congress to pass a measure that in their view has some teeth, including background checks, a ban on assault weapons and a closure of the so-called "gun show loophole."
