The House Oversight and Government Reform Committee will meet on Friday to decide whether IRS official Lois Lerner waived her right to avoid self-incrimination by reading a statement before the panel in May, Politico reported Tuesday.

If the committee determines that Lerner waived her Fifth Amendment rights by declaring her innocence, she could be summoned to reappear before the panel to answer questions about the IRS’s targeting of conservative groups, among others.

Lerner, director of the IRS’s Exempt Organizations division, has been on administrative leave since late May.
