WASHINGTON (AP) — House Republicans put forth a $2.2 trillion "fiscal cliff" counteroffer to President Barack Obama on Monday, calling for raising the eligibility age for Medicare, lowering cost-of-living hikes for Social Security benefits and bringing in $800 billion in higher tax revenue — but not raising rates for the wealthy. The White House declared the Republicans still weren't ready to "get serious."

With the clock ticking toward the year-end deadline, House Speaker John Boehner, R-Ohio, and other Republicans said they were proposing a "reasonable solution" for negotiations that Boehner says have been going nowhere. Monday's proposal came in response to Obama's plan last week to raise taxes by $1.6 trillion over the coming decade but largely exempt Medicare and Social Security from budget cuts.

Though the GOP plan proposes to raise $800 billion in higher tax revenue over the same 10 years, it would keep the Bush-era tax cuts — including those for wealthier earners targeted by Obama — in place for now. Dismissing the idea of raising any tax rates, the Republicans said the new revenue would come from closing loopholes and deductions while lowering rates.
