Shift in public opinion and new found political will for regulation in wake of Connecticut shooting.
With the Sandy Hook School shootings still very fresh in the hearts and minds of Americans, Washington has new momentum for more gun control laws, and the White House says President Obama fully intends to use it.
House Minority Leader Nancy Pelosi will meet with the Brady Campaign and victims from other mass shootings on Tuesday.
She wants to renew the ban on assault weapons.
The Senate held a vigil Monday night after moments of silence in both chambers.
The Senate has already announced gun control hearings early next year.
"We need to accept the reality that we are not doing enough to protect our citizens," said Senate Majority Leader Harry Reid.
Since the shootings there has been renewed interest on Capitol Hill to take gun control off the back burner.
"It just really has changed us. It changed me," said West Virginia Senator Joe Manchin.
Manchin and others who've backed the National Rifle Association in the past now say they're re-thinking their views.
"I don't know of anybody that goes hunting with a assault rifle. I don't know anybody that needs those types of multiple clips as far as ammunition in a gun," Manchin said.
Connecticut Congressman Chris Murphy says it's long overdue.
"The tipping point should have happened a long time ago," he said.
President Obama met with cabinet members Monday promising a "comprehensive solution" as protesters demonstrated outside the National Rifle Association's office.
The group has been silent since Friday's shootings.
A Washington Post poll taken after the shootings finds 54 percent favor tougher laws, but seven in ten oppose a ban on handguns.
