For nearly 20 years, Congress has pushed the Centers for Disease Control and Prevention (CDC) to steer clear of firearms violence research. As chairman of the appropriations subcommittee that traditionally sets CDC funding, Kingston has been in a position to change that. Soon after Sandy Hook, Kingston said he had spoken to the head of the agency. “I think we can find some common ground,” Kingston said.

More than a year later, as Kingston competes in a crowded Republican primary race for a U.S. Senate seat, the congressman is no longer talking about common ground.

In a statement to ProPublica, Kingston said he would oppose a proposal from President Obama for $10 million in CDC gun research funding. “The President’s request to fund propaganda for his gun-grabbing initiatives though the CDC will not be included in the FY2015 appropriations bill,” Kingston said.

Rep. Steve Womack (R-AR), the vice chairman of the subcommittee, also “supports the long-standing prohibition of gun control advocacy or promotion funding,” his spokeswoman said.
