(CNN) - Republicans using the Internal Revenue Service scandal to slam health care reform have a new twist in their argument.
Sarah Hall Ingram, who heads the implementation of the Affordable Care Act at the IRS, formerly led the agency's tax exempt/government entities division, the same division that's now taking heat for targeting conservative groups in the past few years.
An IRS spokesperson confirmed Ingram is the current director of the Affordable Care Act office, a department she’s worked in since December 2010. Meanwhile, a 2009 posting on the IRS website referred to her as the commissioner for the tax exempt/government entities division.
The IRS admitted last week it began over-scrutinizing conservative groups in 2010.
Joseph Grant, her successor, began acting as division commissioner in December 2010, the IRS spokesperson said, and earlier this month he was officially named commissioner.
Earlier Thursday, he became the second IRS official this week to announce his resignation. Grant plans to retire June 3, according to an internal memo for IRS employees that was obtained by CNN.
Before directing the tax exempt division in 2009, Ingram served as chief of appeals at the IRS for three years and as counsel/associate chief counsel for the tax exempt division. She started at the agency in 1982.
The Republican-led House of Representatives passed a measure to repeal Obamacare entirely on Thursday for the third time.
But the latest scandal involving the IRS, one of the key agencies charged with enforcing the health care law, is adding fuel to the political fire over the controversial law.
And Congressional Republicans are already citing the new development about Ingram as another reason why health care needs to be rolled back.
Thursday's vote was the 37th time the House has attempted to eliminate all or parts of the law.
“Stunning, just stunning," was all Senate Minority Leader Mitch McConnell had to say about the revelation Ingram previously led the tax exempt division.
Sen. John Cornyn, R-Texas, introduced a bill to "prohibit" the Treasury Department from enforcing the Affordable Care Act. The legislation, which has little chance of passing in the Democratic-led Senate, is titled "Keep the IRS Off Your Health Care Act of 2013."
The recent IRS scandal "raises pertinent questions about the agency's ability to implement and oversee" the health care law, according to the legislation.
