TOPEKA, Kan. (AP) -- The Kansas Republican Party wants an investigation into a former Democratic lawmaker's use of official-looking letterhead for committee testimony.

The Topeka Capital-Journal reports (http://bit.ly/X9rwZI ) that state GOP Executive Director Clay Barker said Thursday that the party will ask Shawnee County District Attorney Chad Taylor to investigate former Rep. Ann Mah of Topeka.

Both Mah and Taylor are Democrats. Mah lost her race for re-election last year by 21 votes.

Mah has spoken several times in committee hearings, providing testimony on stationery featuring a drawing of the Statehouse and identifying her as a state representative. Barker noted that state law makes it a misdemeanor to impersonate a public official.

Mah scoffed at the criticism. She said the GOP is trying to keep her from winning back her seat next year.
