OMAHA, Neb. (AP) — Another Nebraska Republican leader 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.

U.S. Sen. Ben Sasse said it’s hard for him to see how the education board can operate effectively while Pat McPherson is still a member of it.

Sasse joined Nebraska Gov. Pete Ricketts in calling for McPherson to resign.

McPherson’s blog, “Objective Conservative,” had included repeated references to Omaha as a “half breed.”

McPherson has said he didn’t write the offending posts and disavowed them before taking the blog down this week. McPherson has said he will not resign.
