A bipartisan Senate proposal to expand background checks for gun buyers gained the backing of one Republican and the potential support of a second Sunday as sponsors said the vote expected this week was too close to call.
The plan would “strengthen the background-check system without in any way infringing on Second Amendment rights,” Maine Sen. Susan Collins said in a statement explaining her support for the measure. But she added that “it is impossible to predict at this point” what will be in a final bill.
Arizona Sen. John McCain, who has a B+ rating from the National Rifle Association, said he was “very favorably disposed” to the proposal that has emerged from Sens. Patrick Toomey, R-Pa., and Joe Manchin, D-W.Va.
“I appreciate their work,” McCain said. “And the American people want to do what we can to prevent these tragedies. And there’s a lot more that needs to be done, particularly in the area of mental health.”
It was in McCain’s home state that a gunman with schizophrenia shot then-Rep. Gabrielle Giffords in the head during a 2011 rampage in Tucson that left six people killed.
Collins and Sen. Mark Kirk of Illinois are the only two Republicans besides Toomey who are expected to vote for the compromise as of now.
It will take 60 votes to pass, meaning that more Republicans will have to come on board because some Democrats from gun-friendly states are expected to oppose the measure.
