In the wake of the deadly Connecticut school shooting, Rep. Carolyn McCarthy said she has warned the White House “the gloves are off” if President Obama fails to act on the issue.

McCarthy (D-N.Y.), the foremost gun control advocate in Congress, said she spoke with White House Chief of Staff Jack Lew before Election Day and told him she will exert pressure on the White House to push for gun control legislation.

“I said, ‘Jack, I know the president is going through an election and I’m telling you after the election I’m coming out full force,’” McCarthy told POLITICO Friday. “I was just giving the White House a heads up that the gloves are off on my side and I was going to do everything I possibly could. … If that meant embarrassing everybody, that’s what I would do.”
