IRS official to testify before House Oversight next week

Wolin in particular could face close questioning, after George told the House Ways and Means Committee on Friday that he had informed the deputy secretary of the audit in June 2012.

George and Shulman are also scheduled to testify before Senate Finance on Tuesday, in what's shaping up as another busy week in the uproar over the IRS.

They will be joined by Steven Miller, the ousted acting IRS chief who got into more than a couple sparring matches with Republicans on Friday in the first hearing looking into the IRS.
