DES MOINES, IOWA -- Iowa Republican Party Chairman A.J. Spiker is urging the state's two GOP congressmen to vote against the fiscal cliff bill approved by the U.S. Senate.

The Associated Press reports that Spiker released a statement Tuesday asking U.S. Reps. Tom Latham and Steve King not to support the measure.

Spiker argues that the proposal would raise taxes without meaningful spending cuts. He also praised Republican U.S. Sen. Chuck Grassley for his vote against the legislation.

Democratic U.S. Sen. Tom Harkin also voted no on the fiscal cliff budget package, saying it helps the wealthy at the expense of the middle class.

U.S. Rep. Bruce Braley, a Democrat, said in a statement Tuesday that he'll support the measure in its current form.
