Conservative groups targeted by the Internal Revenue Service are telling their side of the story to Congress.
    
Several of the groups say their applications for tax-exempt status were delayed and that agents asked intrusive and unnecessary questions about who gave them money, their political views, and even how they prayed.
    
Leaders of six of the groups are testifying in front of the House Ways and Means Committee, one of three congressional committees investigating the IRS scandal. The Justice Department is conducting a separate criminal investigation.
    
Meanwhile, acting IRS Commissioner Daniel Werfel says he knows the agency has to correct its problems.

"The agency stands ready to confront the problems that occurred, hold accountable those who acted inappropriately," Werfel said.

But Republicans, far from satisfied, want to see just what action the IRS will take.
