TOPEKA, Kan. (AP) _ Former U.S. Rep. Jim Slattery plans to file Tuesday for the U.S. Senate.
Slattery kicked off his campaign for the Democratic nomination more than a month ago, and he has been traveling the state.
But his bid won't become official until he files the necessary paperwork at the secretary of state's office. He plans to be there at 9:30 a.m.
He's coming with one of his sons, Mike, who is running for a seat in the Kansas House from Johnson County.
Slattery hopes to win the right to challenge Republican incumbent Sen. Pat Roberts. But he'll first face Lee Jones, an Overland Park railroad engineer and labor union activist, in the Aug. 5 primary.
Slattery represented the 2nd District of eastern Kansas in 1983-94.
