In the wake of the reported targeting of conservative groups by the Internal Revenue Service, congressional Republicans unveiled legislation Monday that would require the agency to fire employees found targeting such groups.

Rep. Mike Turner (R-Ohio) and Sen. Marco Rubio (R-Fla.) unveiled matching bills in the House and Senate Monday that would require the IRS to fire any employee found "willfully" violating "the constitutional rights of a taxpayer," according to statements by both lawmakers.
