A "conservative-leaning" organization, the National Law and Policy Center, has filed an ethics complaint against Senator Lisa Murkowski.   This stems from the land purchase she made from a political supporter -- a story broken by our friends at TPMmuckraker just last week.  Now, an ethics complaint from an ethics watchdog: 

A government watchdog group filed an ethics complaint Wednesday against U.S. Sen. Lisa Murkowski, charging that her 2006 purchase of an exclusive Kenai riverfront lot was a “sweetheart deal” from Anchorage businessman Bob Penney.

The complaint, brought by Ken Boehm, chairman of the conservative-leaning National Law and Policy Center of Falls Church, Va., also charged that Murkowski filed false information about the land deal on her annual financial disclosure and obtained special treatment on a mortgage from the Ketchikan bank where her sister serves as a director.

Murkowski spokesman Kevin Sweeney said the senator would have no comment Wednesday. Penney said from his summer home on the Kenai River outside Soldotna that he wouldn’t comment, either.
