Expanding background checks for gun purchases can still happen, Sen. Joe Manchin (D-W.V.) told "Fox News Sunday."

Manchin said he spoke to Sen. Pat Toomey (R-Pa.) at Saturday night's White House Correspondents' Association Dinner and that his partner on the legislation was ready for another try. In a vote earlier this month, the bipartisan amendment failed to get the 60 votes necessary for passage.

"I don't think he's done," Manchin said. "I was with Pat last night, and Pat's totally committed to this bill. And I believe that with all my heart. And we're gonna work this bill."

The senator told host Chris Wallace that he "absolutely" plans to bring it back to the floor for another vote. "I truly believe that if we have time to sell the bill and if people will read the bill" it can pass, he said.
