Committee Chairman Darrell Issa, R-Calif., said he might recall her. He and other Republicans say they believe she forfeited her Fifth Amendment privilege not to testify by giving an opening statement in which she proclaimed her innocence, but several law professors were skeptical they could make that stick.
Issa later said he would consult with others — including her lawyer and House attorneys — before determining whether to summon her again, hopefully deciding by the time Congress returns early next month from an upcoming recess.
"She's a fact witness with a tremendous amount that she could tell us," Issa said.
Lerner, a career civil servant, is still in her position at the IRS. She was the IRS official who first publicly disclosed the matter at a legal conference on May 10.
J. Russell George, the Treasury Department inspector general for tax administration, has blamed ineffective management for allowing agents to improperly target conservative groups for so long.
On Wednesday, he hinted there may be more revelations to come. He told the oversight committee that his office has since uncovered other questionable criteria used by agents to screen applications for tax-exempt status. But he refused to elaborate.
"As we continue our review of this matter, we have recently identified some other BOLOs that raised concerns about political factors," George said. "I can't get into more detail at this time as to the information that is there because it's still incomplete."
