House Republicans have lined up with Democrats to brush aside a threatened White House veto and approve a one-year moratorium on a series of Bush administration restrictions on how states spend federal Medicaid money. The moratorium passed by a vote of 349-62, about 75 votes more than the two-thirds majority needed to override a veto. The Bush adiminstration says the restrictions are needed to rectify waste and abuse. Supporters of the moratorium say the new regulations would shift too many costs to the states and the poor.
