A storm brewing in the Caribbean brought the effort to plug the ruptured oil well to a near standstill Wednesday. Work on the relief well — now just days from completion — was suspended. If conditions get too stormy, the cap that has been keeping the oil bottled up since last week might have to be reopened, allowing crude to gush into the Gulf again for days. A federal judge stopped companies from developing oil and gas wells on billions of dollars in leases off Alaska’s northwest coast, saying the federal government had failed to follow environmental law before it sold the drilling rights. A Washington Post analysis found that 3 out of every 4 lobbyists representing oil and gas companies previously worked in the federal government. That exceeds the overall average of fewer than in 3 registered lobbyists in 2009 who had such government connections, the Post said. Four major oil companies — not including BP — agreed to pool $ billion to form a new company that would respond to offshore oil spills.
