NORTH LITTLE ROCK — Former North Little Rock Mayor Pat Hays is expected to announce he will run for the 2nd Congressional District next year.

Hays will be the first candidate to formally launch a bid for the central Arkansas seat since Republican U.S. Rep. Tim Griffin said Monday he will not seek a third term.

Hays is set to announce Tuesday afternoon in North Little Rock that he'll seek the Democratic nomination for the seat.

Several Democrats and Republicans have said they're considering a run for Griffin's vacated seat.

Hays was North Little Rock's longest-serving mayor, taking office in January 1989. He opted against running for re-election last year.
