(BP oil spill story updated for new leak in BP cap, losses in Transocean, Anadarko shares)NEW YORK ( TheStreet) -- The White House announced Monday afternoon that BP's much ballyhooed well cap is now leaking at the top, along with seepage some two miles away, according to the Associated Press. Government officials are also monitoring bubbles that can be seen using deepsea cameras. The latest issues since the initial cap success on last Thursday signal that the cap could be coming off sooner rather than later. However, if BP's improved siphoning system works, by BP's estimates it should be able to handle up to 80,000 barrels of oil daily, more or less able to handle all of the oil flow coming out from the leaking Macondo well. The White House report was the latest piece of news in an already down day for BP ( BP), whose shares began the week trading down on Monday by close to 5%, and the oil spill stock was taking shares of Transocean ( RIG) and Anadarko Petroleum ( APC) down with it. New tensions surfaced over the weekend related to the successful BP effort to cap the well, with BP and the federal government expressing different views about the potential for dangerous seepage at the seafloor near the Macondo well. Last Thursday afternoon, BP shares surged 7.5% in late trading, when its cap successfully stopped the flow of oil into the Gulf of Mexico. However, Friday selling in BP shares, coupled with Monday morning's negative trading, erased those gains, bringing BP shares back to the under-$36 share price at which they were trading last Monday. It's not a big surprise that BP shares have taken a step back since last Thursday's rally, since the issues at the crux of BP's liability in the Gulf have not changed as a result of the cap. The latest tussle between the government and BP over the cap only compounds that existing uncertainty.
