My daughter was killed on live television. I will do whatever it takes to end gun violence.

I plan to devote all of my strength and resources to seeing that some good comes from this evil. I am entering this arena with open eyes. I realize the magnitude of the force that opposes sensible and reasonable safeguards on the purchase of devices that have a single purpose: to kill.

That means we must focus our attention on the legislators who are responsible for America’s criminally weak gun laws; laws that facilitate the access dangerous individuals have to firearms on a daily basis.

Legislators such as Rep. Bob Goodlatte (R-Va.), who represents Roanoke, where the shooting of my daughter and her colleague Adam Ward took place on live television. In his more than two years as chairman of the Judiciary Committee, Goodlatte has had plenty of opportunity to bring up universal background check legislation and other gun violence prevention bills. He has refused to lead on this issue, and he has done absolutely nothing to help contain the carnage we are seeing. On the other hand, Goodlatte had no problem cashing his check from the National Rifle Association during the 2014 election cycle. Shame on him.
