Transcript for Lawmakers Let Loose on Ex-IRS Chief During Congressional Testimony
Tonight, finally, the irs tries to explain itself. And it comes after a week of scandal and mounting questions about fairness and singling out conservatives. So, what is their answer to the american public? And what about the blast of outrage they had to face today? Abc's chief white house correspondent jonthathan karl tells us.
