The search for the missing Malaysia Airlines jet is being widened.  Australia's deputy prime minister said the decision is being made after French satellite images showed what could be floating debris.   Deputy Prime Minister Warren Truss said the new lead is promising but cautioned the search remains difficult in the southern Indian Ocean.  He says the forecast for Monday's search "is not that good" and "it's going to be a challenge." 

There are now ten planes involved in the search including aircraft from China and Japan. Truss says the object that was spotted by a French satellite was over 500 miles north of the current search area. The Boeing 777 disappeared on March 8th with over 230 people on board. 

A U.S. official says there's no overarching theory about the Malaysian airliner's disappearance. Deputy national security adviser Tony Blinken told CNN's "State of the Union" searchers are still gathering information.  

The Chairman of the House Committee on Homeland Security feels the search should have gone to the Indian Ocean sooner. Texas Republican Mike McCaul told "Fox News Sunday" Malaysian authorities wasted a week looking in the Gulf of Thailand. He also said he still believes there's no firm evidence of terrorism.  Australia's prime minister says new satellite data could help center the search area.
