Oil runs so deep in American life that when President Barack Obama formed an independent commission to investigate the Gulf spill, he ran into something of an oil patch of his own.

Both commission chairmen had stock in BP as well as broader interests in the oil industry. Another commissioner, a university fundraiser, is chancellor at a school that received millions from BP. Another had substantial ties to Transocean, owner of the Deepwater Horizon rig that exploded in the Gulf of Mexico and set off the spill.

The Justice Department has concluded its two-year investigation into the Bush administration's firing of U.S. attorneys and will file no charges, people close to the case said Wednesday.

The investigation looked into whether the Bush administration dismissed the nine U.S. attorneys as a way to influence investigations. The scandal contributed to mounting criticism that the administration had politicized the Justice Department, a charge that contributed to the resignation of Attorney General Alberto Gonzales.

Abortion foes have won a round in the first test of how President Barack Obama's health care law will be applied to the politically charged issue. Meanwhile, traditional allies of the administration are grumbling about a decision to ban most abortion coverage in insurance pools for those unable to purchase health care on their own.

The Catholic bishops "welcome this new policy," said Cardinal Daniel DiNardo, although he added the organization remains concerned that other parts of the health care overhaul will promote abortion.

At the moment, oil and gas companies are on track to shatter their record of total contributions from the last non-presidential election cycle, in 2006—despite the lingering effects of the economic downturn. Halfway through the election calendar, the industry is on pace to spend more than $27 million—the most ever in a campaign year not involving the White House.

With the stakes in Congress so high—from health care to financial regulation—the jump in spending is mirrored in other industries as well. Oil still lags behind 13 other industries in its Washington largesse.
