Families of the victims of last month's shooting attack at a Connecticut elementary school have been invited to the White House Wednesday to see President Barack Obama outline an effort aimed at reducing gun violence.

The president is expected to speak at 11:45 a.m.  Watch the press conference live here.

   Obama's ideas include bans on military-style assault weapons and high-capacity ammunition magazines, but he would need congressional approval for that.

Obama is also taking steps on his own, including efforts to boost availability of mental health services.

   He may also order the Justice Department to crack down on people who lie on gun-sale background checks.

   In advance of today's event, the National Rifle Association has released an online video calling Obama an "elitist hypocrite" for having armed Secret Service agents protect his daughters at school while not committing to installing armed guards in all schools.

   There's a new Associated Press poll that indicates nearly six in 10 Americans want stricter gun laws in the aftermath of the shooting.

Tuesday night, New York lawmakers passed the toughest gun control bill in the nation. Mass shooting victims hope a similar bill is enforced nationally.

"Mentally ill people with guns, come on. It's a lethal combination," said Lonnie Phillips, father of an Aurora, Colo. theater shooting victim.

In response, there are talks among gun rights advocates about the possibility of trying to impeach Obama if the gun control measures go too far.
