Colorado Ethics Watch filed a complaint Tuesday against Aurora City Councilman Ryan Frazier, saying he failed to file accurate information on his financial disclosures.

The complaint to the Aurora city clerk said he did not report leaving Raytheon for Avaya and later becoming a partner at Takara Systems, from which he says he receives no income.

Frazier, a Republican who is expected to announce soon his run for U.S. Senate in 2010, said he announced at a council meeting that he had switched jobs but failed to do so in his finance reporting.

"The financial-disclosure requirement exists because citizens deserve to know where an elected official's allegiances lie," Colorado Ethics Watch director Chantell Taylor said in a statement. "How else can the public scrutinize potential conflicts of interest?"

Colorado Ethics Watch has been tied to the Colorado Democracy Alliance, a group of liberal power-donors supporting Democratic candidates and causes through a network of nonprofit and political groups. Ethics Watch has declined to reveal how it is funded.

Frazier called the error unintentional.

"It was a slight oversight that is now being corrected," he said.
