WASHINGTON - Conservative senators from both parties announced their support for expanding background checks for gun buyers Wednesday, giving a burst of momentum to advocates of stronger restrictions. But big questions remain about whether President Obama can push significant gun controls through Congress.
The compromise between Sens. Joe Manchin, D-W.Va., and Patrick Toomey, R-Pa., boosted the chances that the Senate will agree to broaden required background checks, a step gun-control groups laud as an effective way to keep weapons from criminals and the mentally ill.
The senators are among the most conservative members of their parties, both have received A ratings from the National Rifle Association, and their endorsements could make it easier for hesitant colleagues to back the effort.
Gun-control advocates still face opposition from many Republican senators and resistance from moderate Democrats, including several facing re-election next year in GOP-leaning states. In the Republican-run House, leaders have shown little enthusiasm for Obama's ideas, making that chamber an even higher hurdle.
Under the agreement the two senators announced at the Capitol, background checks would be expanded to all for-profit transactions, including sales at gun shows and online, with records kept by licensed gun dealers who would handle the paperwork. Exempted would be noncommercial transactions such as between relatives. Currently, the system applies only to sales by the country's 55,000 federally licensed firearms dealers.
The agreement also contains provisions expanding firearms rights, and that concerns gun-control supporters. Some restrictions on transporting guns across state lines would be eased, sellers would be shielded from lawsuits if the buyer passed a check but later used a firearm in a crime, and gun dealers could conduct business in states where they don't live.
"Truly the events at Newtown changed us all," said Manchin, citing the Connecticut town where December's murders of 20 first-graders and six educators propelled gun control to the top rank of national issues. "Americans on both sides of the debate can and must find common ground."
Emotion, always prominent in the gun issue, cropped up late Wednesday when Manchin met with relatives of the Newtown victims in his Senate office, telling them that "this will not be in vain."
He became choked up when a reporter asked about the impact of the family members' visit, saying, "I'm a parent, a grandparent ... and I had to do something."
Said Toomey: "Criminals and the dangerously mentally ill shouldn't have guns. I don't know anyone who disagrees with that premise." He said that expanding the checks wasn't gun control, "just common sense."
The agreement makes it all but certain that the Senate will reject a conservative blockade and vote today to begin debating Democrats' gun legislation. Besides broader background-check requirements, the bill would toughen laws against illicit firearms sales and provide a small increase in school security aid.
Underscoring that the fight was far from over, NRA spokesman Andrew Arulanandam said the organization opposes the Manchin-Toomey accord. The group, which has fought most of Obama's gun proposals and claims nearly 5 million members, said the focus should be on improving the nation's mental health system and sources of violence like gangs.
"Expanding background checks at gun shows will not prevent the next shooting, will not solve violent crime and will not keep our kids safe in schools," the NRA said.
Also criticizing the deal was conservative Sen. Tom Coburn, R-Okla., who participated in a failed effort with Sen. Chuck Schumer, D-N.Y., to reach a separate compromise. Coburn called the Manchin-Toomey effort a "good-faith but unworkable plan" that "prioritizes collecting records over protecting citizens."
House Speaker John Boehner, R-Ohio, repeated his view that the Senate should act, saying, "It's one thing for two members to come to some agreement. It doesn't substitute the will for the other 98 members."
In a written statement, Obama said he'd prefer stronger language than the compromise, but he said it represented progress.
Obama also favors bans on assault weapons and high-capacity ammunition magazines - which seem to have little chance of winning approval in the Senate, let alone the House.
