Rep. Joe Walsh, R-Ill., a freshman congressman who campaigned heavily on fiscal responsibility issues, is being sued by his ex-wife for $117,437 in allegedly unpaid child support. The lawsuit charges that Walsh loaned his campaign $35,000 and paid himself back at least $14,200 while claiming to be unemployed and without money. Walsh’s attorney said he had thought a child-support settlement was in the works and insisted that the congressman owed “much less” than the six-figure amount demanded.
