tony cervoneTony Cervone, who left Volkswagen last year to guide communications at GM during the automaker's recall crisis, has added oversight of the GM Foundation to his duties.

The change comes amid the exit of Bob Ferguson, GM's public policy chief and top lobbyist who also chaired the foundation. Ferguson, who guided CEO Mary Barra through bruising Congressional hearings, is pursuing "external opportunities."

The policy role at GM goes to executive VP and general counsel Craig Glidden, who took that chief legal role in March.

Barra thanked Ferguson for his "significant contributions" to the company.

Cervone took the PR reins last May after GM bounced PR chief Selim Bingol.

The GM Foundation has doled out $265M in grants over the past decade.
