WASHINGTON (AP) _ Jean Hanson, the Treasury Department general counsel, resigned today, the latest casualty of the Whitewater affair.

Hanson's resignation, announced by Treasury officials, came just a day after President Clinton accepted the resignation of Deputy Treasury Secretary Roger Altman, who had been accused of misleading Congress with his Whitewater testimony.

The resignation is effective after Senate confirmation of her successor.

Hanson's resignation letter was addressed to Treasury Secretary Lloyd Bentsen, who said he had recommended to Clinton that she be succeeded by Edward S. Knight, Bentsen's executive secretary and senior adviser.

Hansen, whose veracity was questioned by lawmakers, was accused of failing to assist Altman in correcting his testimony.

Under congressional questioning in February, Altman was the first to reveal Whitewater-related contacts between the White House and Treasury. But at first, he acknowledged just one. He amended his testimony several times later to add more contacts.

Hanson, in her own testimony, suggested Altman and Bentsen knew about the contacts earlier than they had said.

Before her nomination in February 1993, Hanson, 44, was a partner at the New York law firm of Fried, Frank, Harris, Shriver & Jacobson. She received her law degree from the University of Minnesota and a B.A. from Luther College in Decorah, Iowa.
