Too scared to talk is gonna get her in worse trouble.

At a short but contentious congressional hearing on Wednesday, former IRS official Lois Lerner repeatedly invoked her 5th Amendment right not to testify about the IRS targeting of tea party groups. This was the second time Lerner has declined to answer questions put to her by the House oversight committee.

Asked if he was considering a contempt citation against Lerner, Committee Chair Darrell Issa (R-Calif.) said, “that’s certainly something that has to be considered.” He said he hoped to get answers from Lerner, and the committee will continue to seek answers in other places.
