DENVER (KKTV) - The father of one of the lives lost in the Aurora theater shooting has announced his candidacy for Colorado House of Representatives.

Tom Sullivan has been an outspoken advocate for both gun control and victims' rights in the years since his son Alex was gunned down during a midnight showing of "The Dark Knight Rises" on July 20, 2012. He has been on the forefront of several pushes to strengthen gun reform laws in Colorado and is challenging a GOP representative with an "A" grade from the NRA for the seat.

In a statement Monday, Sullivan said he was running to implement the kind of change he couldn't make outside the Capitol.

"You can raise money for somebody. You can make empowered speeches, but when it comes down to it, you don’t really have the ability to make the change unless you’re the one up there making the vote. That’s what I have to do."

Sullivan said he was running "for my murdered son Alex ... because I know that we can do better for my daughter Megan, and everyone in Colorado who needs someone to fight for the regular people and not protect the well-connected political insiders."

Sullivan previously lost a bid for a state Senate seat in 2016.
