Republicans on the House Appropriations Committee blocked a proposal on Wednesday that would allocate $10 million to fund the Center for Disease Control and Prevention's gun violence research, reports Politico.

Between the lines: The party-line vote conflicts with a bipartisan agreement from earlier this year that allows the federal agency to study the issue. Previously, a 1996 measure limited the CDC's capacity to do so. But Republicans say the agency is free to study firearm injuries and argue that funding the amendment would only politicize the 2019 spending bill.
