The National Rifle Association has wasted no time attacking President Obama over his plans for new gun control measures.

The group released a new television commercial Tuesday night charging the president of hypocrisy for being "skeptical" about placing armed guards at schools while his two daughters are protected by the U.S. Secret Service.

The president is expected to unveil his new gun control proposals Wednesday. The move comes after the Dec. 14 massacre at Sandy Hood Elementary School in Connecticut.

Twenty children and six teachers were gunned down in what has been called one of the worse mass shootings in U.S. history.

The president will call on Congress to ban military-style assault weapons, limit the number of bullets allowed in a magazine, and require background checks on nearly every gun purchase.

He said he will also take action without Congress by executive order. At least 19 executive orders on gun control could be enacted.

Victims of mass shootings have also called for gun control reforms.

"Mentally ill people with guns? Come on! It's a lethal combination," Lonnie Phillip, father of an Aurora, Colo., shooting victim, said.

Former Attorney General Ed Meese raised the possibility of impeaching the president if his executive orders on gun control go too far.
