He doesn't know when the next vote may come, but U.S. Sen. Joe Manchin isn't giving up on broader gun buyer background checks.
The West Virginia Democrat continues to seek needed supporters for his proposal to expand checks to commercial settings such as gun shows and online.
Manchin's resolve is reflected in a TV ad that answers one aired by the National Rifle Association. Each has appeared on West Virginia stations this month.
After repeatedly endorsing Manchin, the NRA has attacked him over his role in the Capitol Hill gun debate. Manchin's response ad does not target the group but rather its top leaders, while touting his gun owner credentials.
Manchin also questions why that leadership has gone after him and not the Republican co-sponsor of his background check proposal.
