Freshman U.S. Rep. Joe Walsh, a tax-bashing Tea Party champion who sharply lectures President Barack Obama and other Democrats on fiscal responsibility, owes more than $100,000 in child support to his ex-wife and three children, according to documents his ex-wife filed in their divorce case in December.

“I won’t place one more dollar of debt upon the backs of my kids and grandkids unless we structurally reform the way this town spends money!” Walsh says directly into the camera in his viral video lecturing Obama on the need to get the nation’s finances in order.
