The IRS official who oversaw the unit responsible for the targeting of conservative groups has been placed on administrative leave with pay, a day after she refused to testify at a congressional hearing, Fox News confirms.

Capitol Hill sources said Lois Lerner, the director of exempt organizations, was placed on paid leave Thursday, amid calls from some lawmakers for her to be suspended or fired. In her absence, Ken Corbin, the current deputy director of the submission processing, wage and investment division, will take over her duties, according to an internal IRS memo obtained by Fox News.
