ORLANDO, Fla. -

Sarah Palin is picking sides in a spirited GOP primary featuring two members of Congress.

Palin announced that she is endorsing U.S. Rep. Sandy Adams over U.S. Rep. John Mica in the race for a U.S. House district in Central Florida.

The contest between Adams and Mica is a rarity in Florida, since it pits two sitting members of Congress against each other.

They decided to seek the U.S. House District 7 seat after the Florida Legislature redrew the boundaries to their existing congressional seats.

Palin took a shot at Mica in her endorsement, saying she choose Adams because she isn't involved in back-room dealings in Washington.
