LINCOLN, Neb. (AP) — Nebraska Gov. Pete Ricketts is calling on a state education board member to resign in the wake of bigoted comments about President Barack Obama that appeared on his blog.

Ricketts said Thursday that he was “deeply disappointed” by the posting that referred to Obama as a “half breed.”

State Board of Education member Pat McPherson has disavowed the comments which appeared on his “Objective Conservative” blog.

McPherson says he didn’t write the piece but took responsibility for not editing it before it was posted earlier Monday by someone he wouldn’t name.

Ricketts says he respects the will of voters, but it’s clear the controversy will hinder the State Board of Education from meetings its goals.

The Nebraska Democratic Party had called on Ricketts to condemn the posting.
