MADISON, Wis. -

Wisconsin Attorney General J.B. Van Hollen says a state agent and supervisor are no longer employed after an internal review found they were letting child pornography cases languish.

Van Hollen says they left the state Justice Department Wednesday morning. He wouldn't say whether they were fired or resigned.

DOJ has taken intense criticism in recent weeks after word broke the agency let at least two cases languish for so long the targets allegedly sexually assaulted children before agents acted.

DOJ launched an internal investigation into the matter late January. Van Hollen says the review found no other agents were allowing their cases to sit except the two who left the agency.

Investigators are still reviewing the two's cases to determine how many sat for too long.
