Councilman David Lifferth said his colleague, David Blackburn, failed to disclose that he received gifts from a firm doing business with the city. But County Attorney Jeff Buhman said Wednesday that Blackburn has done nothing illegal.

Lifferth said he is not convinced and wants a third-party review of Buhman's report.

"No one ever denied that Councilman Blackburn received gifts," Lifferth said. "There just wasn't enough evidence."

Mayor Don Richardson disagrees. He said the city attorney reviewed the case and found no wrongdoing. Blackburn was invited to different places, but the value of those invitations did not cause a conflict of interest or violate the law, he said.

"Mr. Blackburn's credibility is intact," the mayor said.

The first investigation began in March at the request of Lifferth, who said Blackburn told him in an e-mail that an engineering firm had given him a free hunting trip.

"As soon as he said that I said, 'Wow, that's very unethical,' and red flags went up," Lifferth said.

When Blackburn refused to disclose the information to the public, Lifferth called for the investigation.

Blackburn maintains that he did nothing wrong and does not know why Lifferth requested the first investigation or wants another review.

"Mr. Lifferth and I haven't gotten along in the past, but you can agree to disagree," he said. "You don't need to go this far.

"I wish he'd direct his interest in things that were more important to the city."
