In what may be a perhaps-almost-final word on the 2013 IRS controversy and alleged targeting of Tea Party groups, a two-year bipartisan Senate investigation found the agency needs to cut through bureaucratic red tape and institute better communication and management.

But members of the Senate Finance Committee, which issued the report, were largely split along party lines on the question of why the IRS went off the rails.

Republicans charged that they were stymied in finding out "the full extent of Treasury Department and White House involvement." Democrats called it "not a matter of political targeting, rather one of gross mismanagement."

The Senate committee, unlike several House probes memorable for their vitriol and snark, kept a low profile. It produced a report with many bipartisan findings, plus a 90-page timeline of the IRS actions.

Among the committee's recommendations:

  • More IRS and Treasury Department employees should be barred from partisan political activity, even on their own time. Republicans allege that former IRS official Lois Lerner, head of the Exempt Organizations section that handled the 501(c)(4) applications, was pursuing her own liberal agenda — something she denied in congressional testimony;
  • The IRS should keep better track of how tax-exempt applications move through the system. Some of the conservative groups saw their applications sit in limbo for months;
  • Upper management should be kept in the loop. The report says Lerner failed to alert her superiors as her section began grappling with the influx of applications.

This all goes back to the scrutiny the IRS gave to politically active "social welfare" organizations between 2010 and 2013. Conservatives allege that mainly Tea Party groups were targeted. The controversy led to a housecleaning at the top of the IRS — also, to a collapse in the agency's already feeble attempts to enforce its existing rules on political activity by 501(c)(4) social welfare groups.
