Democrats on the oversight committee release the full transcripts that Issa refused to. It's pretty obvious why Issa didn't want to release them:

Democrats on the House Oversight Committee on Tuesday released a full transcript of testimony from a witness in the IRS targeting investigation, which appears to confirm that the initial activity originated with a low-level employee in the agency's Cincinnati office, according to the Washington Post.

The transcript shows a key witness, a self-described conservative Republican and IRS manager who supervised the screens of applications for tax exempt status, claiming that he had no communication with the White House or senior IRS officials about the targeting.

His testimony contradicts House Oversight Committee chairman Rep. Darrell Issa’s (R-CA) previous suggestion that the order to target conservative groups came from Washington. Issa has since refused to release the full testimony transcripts, prompting Democrats on the committee to do so on their own.
