LINCOLN, Neb. (AP) — A Republican state senator and former speaker of the Legislature is challenging Congressman Jeff Fortenberry who is facing federal charges as he runs for re-election.

State Sen. Mike Flood, of Norfolk, announced Sunday that he will challenge Fortenberry in the state’s First Congressional District. Flood will face off against Fortenberry, who has held the seat since 2005, in the May primary.

Fortenberry has pleaded not guilty to allegations that he misled federal authorities who were investigating an illegal donation to his campaign from a foreign national in 2016.

Fortenberry was already facing a challenge from Democratic State Sen. Patty Pansing Brooks.
