Two Internal Revenue Service agents working in the Cincinnati office say higher-ups in Washington directed the targeting of conservative political groups when they applied for tax-exempt status.IRS officials have repeatedly said the targeting was initiated by front-line agents in the Cincinnati office and was stopped once senior officials in Washington found out.The agents did not provide proof that senior IRS officials ordered the targeting. But one of the agents says her work processing the applications was closely supervised by a Washington attorney in the division that handles applications for tax-exempt status. The agents were interviewed by congressional investigators. The Associated Press reviewed transcripts of the interviews.
