TOPEKA, Kan. (AP) — Kansas Governor Sam Brownback's office says federal prosecutors have brought no charges after completing their investigation into loans that the state's lieutenant governor made to the ticket's re-election campaign. In a statement, the governor's office said the U.S. attorney's office was bringing no charges after completing its investigation "regarding campaign finance matters." Lt. Gov. Jeff Colyer did not respond to messages from the Associated Press seeking comment. A spokesman for the U.S. attorney's office had no immediate comment. The three loans totaling $1.5 million raised eyebrows not only because their size is unusual in Kansas politics but because the first two were repaid within days. Some Democrats speculated the loans were an attempt to bolster Brownback's fundraising totals to make the campaign appear in better shape.
