The Hill's Roxana Tiron reports, Rep. Todd Tiahrt (R-Kan.) was among seven lawmakers cleared of wrongdoing by the House ethics committee Friday.

Tiahrt had been accused of exchanging earmarks for campaign contributions with the now-defunct lobbying firm PMA Group. The House ethics report said that investigators found no evidence that any lawmaker was banking on campaign donations when making decisions about earmarks that benefited PMA clients.

Tiahrt, who's running for the GOP Senate nod in Kansas against Rep. Jerry Moran, called the committee's report "absolute vindication."

"This comes as no surprise because there was never anything to justify a review in the first place," he said in a statement. "The process referenced in the report reflects the same professional and objective procedures followed in my office for reviewing and requesting defense-related projects for Boeing and other reputable Kansas-based companies that employ thousands of Kansas workers in my district."

Despite the report, Moran officials say the issue isn't going away.

"The fact there's not apparently an ongoing inquiry by Congress, we don't think that takes away from the manner in which Tiahrt has operated in the Congress for many years,” a senior Moran campaign official said on background. "You will hear more from us on that."
