A decision about a critical pressure test would be made at midday, officials said, and the drilling of a relief well in the gulf would be halted as a precaution.
AP - BP's work to cap its Gulf of Mexico gusher was in limbo Wednesday after the federal government raised concerns the operation could put damaging pressure on the busted well and make the leak worse.
The CIA has lost one of its most valued former spies. Iranian nuclear scientist Shahram Amiri, who defected to the US, is now on his way back home to Tehran after a very messy and public re-defection. ABC News obtained exclusive photos of Amiri leaving Washington's Dulles International Airport late Tuesday night on a commercial flight to Doha, Qatar, en route to Iran.
The government is expected to announce the "integrity test" on the ruptured Gulf oil well will go forward, barring objections from scientists, a BP source tells CNN.
Shahram Amiri -- a nuclear scientist Tehran claimed was kidnapped by U.S. agents -- told a state-run television station in Iran that he was abducted by U.S. intelligence officials and faced "psychological warfare and pressure that are much worse than being in prison."
