Barack Obama moves to tighten background checks, gun sales

The White House unveiled gun control measures on Monday that require more gun sellers to get licences and more gun buyers to undergo background checks, moves President Barack Obama said were well within his authority to implement without congressional approval. 

The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives now will require that people who sell guns at stores, at gun shows or over the internet be licensed and conduct checks, officials said. The ATF was finalizing a rule requiring background checks for buyers of dangerous weapons from a trust, corporation or other legal entity as well.

• Republicans, Democrats criticized over San Bernardino prayers and gun reform
• Gun sales to people on FBI terrorist watchlist must be blocked, Obama says

Obama, speaking to reporters before the measures were made public, said they were consistent with the U.S. Constitution's Second Amendment, which protects the right to bear arms.

"These are not only recommendations that are well within my legal authority and the executive branch, but they're also ones that the overwhelming majority of the American people, including gun owners, support," Obama said during a meeting with Attorney General Loretta Lynch and other advisers.

Obama is igniting a political firestorm by bypassing Congress with the measures, which could spark legal challenges.

Gun maker shares soar

Republicans say Obama is misusing his powers.

Shares in gun makers Smith & Wesson Holding Corp and Sturm Ruger & Co Inc rose against a falling stock market on Monday in anticipation of increased gun sales, as has happened before when the White House mulled weapon sales reform.

Stymied by Congress's inaction on gun control, the president asked his advisers in recent months to examine new ways he could use his executive authority to tighten gun rules unilaterally after multiple mass shootings generated outrage nationwide. The White House had drafted a proposal on licences previously but was concerned it could be challenged in court and hard to enforce.

Guns are a potent issue in U.S. politics. The National Rifle Association, the top U.S. gun rights group, is feared and respected in Washington for its ability to mobilize gun owners. Congress has not approved major gun-control legislation since the 1990s.

Attorney General Loretta Lynch said the administration did not have an estimate of the number of people who would be affected by the changes. She did not set out a numerical threshold for dealers, telling reporters on a conference call that people selling one or two guns at a flea market could considered be dealers. But she said hobbyists and collectors would still be exempt from registration requirements.

Obama said the measures would not prevent every mass shooting or violent crime, but they did have the potential to save lives. The president is scheduled to give remarks about gun control at 11:40 a.m. ET on Tuesday.

Congress rejected tighter rules in 2013

The president's use of executive action launches his final year with a move that Republicans say exemplifies misuse of his powers.

Congress, which is controlled by Republicans, rejected Obama's proposals for legislation to tighten gun rules in 2013.

"The president is at minimum subverting the legislative branch, and potentially overturning its will," Republican Speaker of the House of Representatives Paul Ryan said in a statement before the White House announcement.

Republicans have called for more focus on mental health care rather than measures to restrict gun ownership.

The White House said it would ask Congress for $500 million in its 2017 budget to boost access to mental health care.

U.S. states have taken their own approaches to addressing gun violence. Texas legalized openly carrying handguns, while New York and Connecticut have banned high-capacity magazines.

In 2008, the U.S. Supreme Court held that the Second Amendment of the U.S. Constitution protects the rights of individual Americans to keep and bear arms. But the court also recognized that laws imposing conditions on commercial guns sale can be consistent with the Second Amendment.
