WASHINGTON (AP) — Acting on the Senate's first budget since President Barack Obama took office, a Democratic-led panel is moving toward party-line approval of a fiscal blueprint that would only modestly trim the budget deficit while protecting safety net programs from slashing cuts proposed by Republicans.

The expected vote Thursday in the Senate Budget Committee comes as Obama arrived at the Capitol for a third consecutive day, carrying his charm offensive with Congress first to Senate Republicans and then his Democratic allies in the House.

The Senate budget plan, drafted by Sen. Patty Murray, D-Wash., blends about $1 trillion in modest cuts to health care providers, the Pentagon, domestic agencies and interest payments on the debt with an equal amount in new revenue claimed by ending some tax breaks.
