Ind. Republican senator to vote no on Manchin-Toomey amendment

Indiana Sen. Dan Coats (R) will vote no on the Manchin-Toomey gun background check compromise amendment, NBC News has learned.

Backers had hoped to win him over. Instead, Coats will introduce his own amendment that also deals with mental illness and school safety.

“I am working with colleagues to introduce in the coming days a comprehensive package that will improve the operation and enforcement of our current background check system, address mental illness in the criminal justice system and improve school safety along with other measures to protect American citizens without violating Second Amendment rights,” Coats said in a statement. “While I appreciate the good-faith effort of Senators Manchin and Toomey, I am concerned their legislation would result in more problems with our existing background check system and would not address the underlying issues with gun violence.”
