DENVER – Denver District Attorney Beth McCann has dropped a grand jury investigation into how Colorado Secretary of State Wayne Williams handles campaign-finance complaints, according to Tuesday morning tweets by Williams.

“We’ve said all along there was no basis for this politically motivated attack,” Williams tweeted.

“We played no favorites and we followed the law,” he later added.

Williams quotes McCann as saying she has requested the grand jury withdraw subpoenas, and that her office “will close the grand jury investigation at this time.”

Ken Lane, a spokesman for Denver District Attorney Beth McCann, told Colorado Politics March 23 there was an “open investigation in the Denver grand jury relating to the Colorado secretary of state, and that it concerns campaign finance complaints and the collection of campaign finance penalties.”

Denver TV station KCNC-CBS4 reported last month that the probe concerned a complaint filed by persistent campaign-integrity advocate Matt Arnold that Williams’ office has improperly intervened in several campaign finance cases that Arnold claims involved Williams’ “associates and political allies,” and that Williams’ staff failed to collect a $9,650 campaign finance judgment against a Colorado Springs political action committee levied by an administrative law judge.

Arnold has frequently filed campaign finance complaints over the years.

Williams had said he was “disappointed” in the investigation, adding that his office has a responsibility to intervene in cases “where the interests of the state, particularly in the proper interpretation and application of campaign finance laws, are an issue.”

Williams, a Republican, is seeking re-election in November. His wife, Holly, is running for El Paso County commissioner.
