House Republican leaders on Tuesday accused President Obama of selling out to corporate America over his decision to delay a key provision in his health care law, vowing to hold another vote aimed at stopping the controversial reforms.

House Majority Leader Eric Cantor, R-Va., said it was “stunning” for the president to declare last week he was giving big businesses a one-year grace period before requiring them to offer health insurance to their employees or pay a penalty, but not offer similar exemptions for families and individuals.

“I never thought I’d see the day when the White House, the president came down on the side of big business but left the American people out in the cold as far as his health care mandate is concerned,” Cantor told reporters after House Republicans met for their weekly closed-door meeting. “And we, as House Republicans, are not going to sit still for that.”

Cantor said the GOP-controlled House will take up a package of bills this month “to stop the government abuse, to put the American people first.” House Speaker John Boehner vowed at least one of those measures will focus on repealing or changing the president’s health care law.

“What the president did is outrageous,” Boehner said. “The idea that we’re going to give big businesses a break on Obamacare but we’re going to punish small businesses and families? It’s wrong. And we’ll have another vote. Count on it.”

The House has voted about 40 times to repeal all or part of the president’s health care reforms since the law was passed in 2010. All have died in the Democratic-controlled Senate.

House Republican leaders also Tuesday sent the president a letter asking him to justify delaying the employer mandate while leaving in place the mandate on individuals and families.

“We agree with you that the burden was overwhelming for employers,” they write, “but we also believe American families need the same relief.”
