The fiancee of Gabe Zimmerman, the staffer for Rep. Gabrielle Giffords (D-Ariz.) who was slain in the January shooting rampage in Tucson, will appear at a Capitol Hill news conference Tuesday morning to endorse House and Senate legislation that would ban high-capacity magazines.

Kelly O’Brien will announce her support for the high-capacity magazine bills at an 11:30 a.m. Capitol news conference with Sen. Frank Lautenberg (D-N.J.) and Rep. Carolyn McCarthy (D-N.Y.), the sponsors of legislation that would ban magazines such as the one used in the Tucson shooting. The news conference will take place in room HC-8 of the Capitol.

The news conference comes as the Brady Campaign is releasing a new TV ad urging President Obama to support the legislation to ban high-capacity magazines. The 30-second ad will run on national cable through the end of the week.

Gun-control proponents have renewed their push for legislation banning the magazines in the wake of the Tucson shooting, which left 13 injured and six dead, including Zimmerman, who served as Giffords’s community outreach director.

But the legislation has not gone far in either chamber. S. 32, the bill introduced by Lautenberg in late January, has been referred to the Senate Judiciary Committee, while H.R. 308, McCarthy’s bill, has been referred to the House Subcommittee on Crime, Terrorism and Homeland Security.

As The Fix noted back in January, polls show that overall public support for stricter gun control laws has decreased since the 1990s, with 44 percent of respondents in an October 2010 Gallup poll saying they favored stricter laws, 12 percent favoring more lax laws and 42 percent saying the laws should remain relatively unchanged.

One piece of data that boosts gun-control advocates’ case: When asked specifically about high-capacity magazines, however, 61 percent of respondents to a CNN poll in January said they favored a ban while 38 percent opposed one.
