WASHINGTON (AP) — One of the Senate's staunchest budget-cutters unveiled Monday a massive plan to cut the nation's deficit by $9 trillion over the coming decade.

The plan by Sen. Tom Coburn, R-Okla., is laced with politically perilous proposals like raising to 70 the age at which people can claim their full Social Security benefits. It would cut farm subsidies, Medicare, student aid, housing subsidies for the poor, and funding for community development grants. Coburn even takes on the powerful veterans' lobby by proposing that some veterans pay more for medical care and prescription drugs.

Coburn was a member of President Barack Obama's fiscal commission and voted for its plan to cut the budget by about $4 trillion over a decade. He recently dropped out of the closely watched "Gang of Six" senators seeking a bipartisan agreement to rein in deficits and break through the partisanship engulfing official Washington over the deficit.
