The latest setbacks:

A Congressional Research Service report commissioned by the House Judiciary Committee says ACORN hasn't violated any federal regulations the last five years.

The report, released by Judiciary Chairman John Conyers' (D-Mich.) staff Tuesday evening, also reports that the undercover filmmakers that allegedly caught employees of the Association of Community Organizations for Reform Now breaking the law may have violated state law in their filming operation.

Separately Tuesday, a New York federal judge rejected a motion from the Justice Department to reconsider a decision that ruled a bill that stopped funding for ACORN as an unconstitutional bill of attainder.
