SAN FRANCISCO (AP) — A Yahoo director embroiled in an investigation into an inaccuracy about CEO Scott Thompson's academic credentials is surrendering her seat on the troubled Internet company's board.

Patti Hart says she decided to not to seek re-election to Yahoo's board to focus on her job as CEO at gambling machine maker International Game Technology. She confirmed her departure in a Tuesday statement issued a few hours after her exit strategy was first reported by All Things D, a technology blog affiliated with The Wall Street Journal.

Yahoo Inc. offered no immediate comment on Hart's decision.

Hart becomes the first casualty of a dust-up caused by the recent exposure of a bogus college degree that has periodically appeared in Thompson's official biography.

Hart led the Yahoo committee that hired Thompson in January.
