(Pittsburgh) -- Some voters and newspapers are asking an Allegheny County state lawmaker to resign because he used fictitious names to attack constituents who support natural gas drilling.

Democratic Representative Jesse White apologized last week for the online attacks first reported by KDKA TV in Pittsburgh, but new details are emerging.

The Observer-Reporter of Washington says a search of their website found that numerous posts by ``Janice Gibson'' came from an Internet address that matches White's personal account. The posts criticized local officials and fellow Democrats Senator Tim Solobay and Representative Brandon Neuman.

A Johnstown Tribune-Democrat editorial says White should resign, and residents have complained to authorities about the attacks. It's not clear if White broke any laws.

Washington County District Attorney Gene Vittone says his office is aware of the issue.
