House probe faults senior IRS officials in tea party controversy; Shows no link to White House

A House Republican probe has failed to show a White House link to a scandal surrounding the mistreatment of conservative groups by the IRS.

The affected groups were seeking tax-exempt status.

The congressionally-based investigation continues, but the report issued Tuesday marks the end of Congressman Darryl Issa's (EYE'-suh) tenure in leading the probe. Issa, a Republican from California, is stepping down as chairman of the House Oversight Committee because of term limits.

Congressman Jason Chaffetz of Utah will take over the committee in January.

The report says conservative groups were given improper scrutiny for more than two years from 2010 to 2012. It complains that the IRS and the White House have not fully cooperated with the investigation.
