In late 2007, Barnes announced she would run in the Democratic primary for Missouri's 6th congressional district, held by four-term Republican Sam Graves.
Graves is the brother of Todd Graves, former U.S. Attorney for the Western District of Missouri.
In October 2008, Senator Kit Bond apologized to Todd Graves, after a U.S. Justice Department report cited Bond forcing Graves out over a disagreement with Representative Sam Graves.
