Here are various links I found that mention Dianne Feinstein is one of them: 1 2 3
After looking into it some more it's possible she no longer carries a loaded handgun personally but it's certain she did at one time. I remember reading that she got a gun to protect herself after Harvey Milk and Moscone were murdered by a police officer. She realized that she couldn't always trust the police to shoot for her since they might be the ones shooting at her. Even if she no longer carries a gun she certainly does so by proxy at taxpayers expense. The rest of us must dial 911, pray the police answer, pray they show up, and pray they don't shoot us if they eventually do.
Speak for yourself. Wisconsin law prohibits concealed carry, so I don't. But it does NOT prohibit having a firearm nearby, so I do. And I don't intend to call 911 first---only later, to pick up the perp's body.
