A report from the Legislative Fiscal Bureau estimates changes to the food stamp program would end benefits for 75,000 clients in Wisconsin.  Democrats called a Tuesday news conference at the Capitol to criticize the SNAP plan being considered by Congress which would add new work and job training requirements for recipients.  The state of Wisconsin would lose almost 24-million of the 867-million dollars in food stamp benefits it received last year.  The Bureau estimates more than 23,000 children would lose their automatic eligibility for free and reduced-cost school lunches.  Parents would have to re-apply.
