A bipartisan coalition on the Senate Appropriations Committee moved Thursday to roll back House GOP-backed cuts to Amtrak, transportation projects, and affordable housing projects, but pressures elsewhere in the budget may make the funding levels unsustainable as the massive $108 billion spending bill moves ahead.
