FILE - This March 22, 2013 file photo shows the exterior of the Internal Revenue Service building in Washington. The Internal Revenue Service long has resisted efforts by an internal watchdog to help groups seeking tax-exempt status, creating a culture that enabled agents to improperly target such organizations for additional scrutiny, the National Taxpayer Advocate reported Wednesday. Nina E. Olson, who runs the independent office within the IRS, said in her annual report to Congress that culture continues today, despite the scandal that has rocked the tax agency for more than a month.
