House Minority Leader Nancy Pelosi (D-Calif.) on Thursday said passage of tougher gun controls is “inevitable,” projecting optimism less than 24 hours after the Senate voted down legislation central to President Obama’s strategy to reduce gun violence.

“It’s a matter of time,” Pelosi said Thursday during a press briefing in the Capitol. “It might be inconceivable to the NRA that this might happen; it’s inevitable to us.”

Pelosi did not put a timeline on her prediction but suggested public outrage over the failed Senate effort will eventually force the opponents of tougher gun laws to reconsider..
