ST. PAUL (AP) — A familiar face in Minnesota politics is back to challenge the state auditor in a Democratic primary.

Former House Minority Leader Matt Entenza filed Tuesday to run against Rebecca Otto, who is seeking a third term.

Entenza, of St. Paul, ran unsuccessfully for governor in 2010. He says he's challenging Otto because she's had a low profile and he thinks Minnesota needs an auditor who will scrutinize education spending and protect pensions that are "under attack."

Otto tells The Associated Press that nothing changes about her intention to campaign hard and tout her record as auditor. She wasn't aware of Entenza's intentions earlier.

DFL Party Chairman Ken Martin calls the last-minute entrance an "insult."

Entenza spent more than $5 million on his run for governor, most of it his own.
