After Mulvaney’s confirmation vote, the Senate is scheduled to take up the nomination of Oklahoma Attorney General Scott Pruitt to head the Environmental Protection Agency. Democrats are calling for a delay on the vote while a court decides whether to force Pruitt’s office to turn over email communications with coal, oil and gas companies. Meanwhile, Republican Senator Susan Collins of Maine said Wednesday she’ll vote against Pruitt. But the defection won’t be enough to derail his confirmation, and Senator Joe Manchin of West Virginia has said he’ll become the lone Democrat to vote in favor of Pruitt.
