In other news from Capitol Hill, Senate Republicans on the Environment and Public Works Committee have announced plans to boycott this week’s work session on a climate change bill, in a move aimed at thwarting Democratic efforts to advance the legislation quickly. Under committee rules, at least two Republicans are needed for Chair Barbara Boxer to hold the work sessions that would give senators an opportunity to amend the legislation and then vote to approve it in the panel. Republicans on the committee include Sen. James Inhofe of Oklahoma, who has described global warming as the “greatest hoax ever perpetrated on the American people.”
