Just hours after news broke of a mass shooting in San Bernadino, Calif., Democratic and anti-gun groups moved swiftly to blame Republicans.

Democracy for America Executive Director Charles Chamberlain called the shooting of at least 28 in the city east of Los Angeles terrorism and blamed easy gun accessibility. He said that because Republicans, and specifically Speaker Paul Ryan, "refuse to stand up to the NRA," then they are complicit with the killers.

"When Paul Ryan and the entire Republican party refuse to stand up to the NRA and the gun industry and pass common sense gun reforms, they are aiding and abetting those terrorists. Period," said Chamberlain.

"In the wake of yet another tragedy, Republicans need to decide: Are you going to stand with the American people and pass common sense gun reform? Or are you going to continue to side with the terrorists who perpetrate these crimes and the merchants of death in the gun industry who make it easier for them to do it?"

Statements from groups backed by anti-gun advocate Michael Bloomberg echoed that statement.

Shannon Watts, founder of Moms Demand Action for Gun Sense in America, said, "thoughts and prayers – particularly from our lawmakers – are simply not enough. To reduce the gun violence that kills 88 Americans and injures hundreds more each day, we must demand our lawmakers act and work to keep guns out of dangerous hands. The phrase 'another mass shooting' doesn't have to be a part of the American vocabulary."

President Obama reiterated his call for new gun laws. During a CBS interview, he said, "There are some steps we could take, not to eliminate every one of these mass shootings, but to improve the odds that they don't happen as frequently, common sense gun safety laws, stronger background checks," he said.

Rep. Debbie Wasserman Schultz, chair of the Democratic National Committee, called on Republicans to join Democrats to limit gun access:

"Our nation's leaders have a moral obligation to prevent the murder of innocent people by enacting reforms to keep guns out of the hands of criminals, the mentally ill, and those on national security watch lists. It is long past time for Republicans to join Democrats to get guns out of the hands of people who should not have them."
