Obama's healthcare, climate goals hit speed bumps

US President Barack Obama suffered a double-barreled setback in Congress on Thursday when members of his own party moved to apply the brakes on his top legislative priorities, healthcare and climate change.

Obama has demanded urgent and simultaneous attention to overhauling healthcare and addressing climate change, saying both were necessary to boost the US economy, which is in a deep recession.

He has demanded that Congress send him a bill by October to cut healthcare costs and provide medical coverage to most of the 46 million uninsured Americans. The president wants climate change legislation before year's end.

While Obama was in Italy on Thursday encouraging world leaders to intensify the fight against global warming, legislation to cut U.S. emissions of greenhouse gases suffered a delay in the Senate.

The leading Senate committee responsible for developing the climate change legislation put off for at least a month work on a bill, leaving less time for Congress to fulfill Obama's desire to enact a law this year.
