WASHINGTON (AP) - The sponsors of a Senate proposal to expand background checks for gun buyers says a vote is likely this week and it's too close to call.
There was a hopeful sign Sunday: Republican Sen. John McCain of Arizona, who has a B+ rating from the National Rifle Association, says he's leaning toward supporting it.
The proposal is from Republican Patrick Toomey of Pennsylvania and Democrat Joe Manchin of West Virginia, and they say it's shaping up as a close call.
The plan would require background checks for people buying guns at gun shows and online. Background checks currently apply only to transactions handled by the country's 55,000 licensed gun dealers.
Toomey says a vote could come as early as Wednesday.
They appeared on CNN's "State of the Union" and CBS' "Face the Nation." McCain was on CNN.
