(Via Politico )   “...Lerner found out in June 2011 that some staff in the nonprofits division in Cincinnati had used terms such as ‘Tea Party’ and ‘Patriots’ to select some applications for additional screening of their political activities.”  (Via  Los Angeles Times )   USA Today reports Lerner was in charge of that Cincinnati office and attempted to correct the target keywords by broadening the language and including criteria, like groups that are “ critical of how the country is being run.”   Lerner was also expected to disclose why she didn’t tell Congress when she first learned of the targeting, but Lerner’s lawyer wrote to the committee saying she didn’t do anything wrong and saw pleading the Fifth as her only option. (Via NBC )   A spokesman for the committee said Lerner is still under subpoena and the committee chair — Representative Darrell Issa — hopes she will change her mind about testifying at the hearing.   Outgoing IRS Commissioner Steve Miller took the stand Tuesday for the second time in two weeks, claiming responsibility for staging the question that led to Lerner’s revelation earlier this month. (Via The Daily Caller )   According to Fox News, the IRS acknowledged they targeted conservative groups at their Cincinnati office, making it more difficult for those groups to get tax-exempt status.
