Yesterday we learned that Rep. Henry Waxman (D-CA) wrote a letter to Special Counsel Scott Bloch urging the embattled chief of the independent investigative office to step down.

Bloch's had a lot of problems lately. He's under investigation by the FBI and his top deputy quit recently complaining about "political agendas" at the office that's supposed to investigate things like misconduct related to political agendas.

Today we see that Bloch promptly fired back, sending Waxman, chairman of the House oversight committee, a terse letter saying he has no plans to resign his post until his term ends next year.
