About a month ago, a strange email hit the inboxes of many congressional staffers. It was an invitation to an ‘Executive Forum’ on climate and energy policy hosted by the American Petroleum Institute. What was strange about this invitation was the sender of the email and the co-host of the policy forum: Newsweek magazine. The event is scheduled for today at 4pm.

Greenpeace’s Executive Director Phil Radford, understandably, took issue with this when the event was announced:

At present, the panel’s only member is American Petroleum Institute (API) President Jack Gerard.As you know, Mr. Gerard is the nation’s top registered lobbyist for Big Oil. API and its biggest member, ExxonMobil, have aggressively lobbied against global warming policy solutions that will inevitably limit global consumption of oil. API and its members have spent tens of millions of dollars over the past decade alone on propaganda efforts and front groups to undercut public confidence in the wide and deep global scientific consensus that global warming is real, that human consumption of fossil fuels is driving it, and that the problem is a serious threat to America and the rest of the world.

Today, Representative Ed Markey pushed this story back to the forefront with a Huffington Post piece. After setting the record straight on Romney’s falsehood and explaining the urgency of clean energy legislation, Markey finishes strong:

So the next time you hear Mitt Romney or other opponents of clean energy and climate legislation railing about the costs of action, you should multiply your suspicion by whatever number they are attempting to sell. Odds are, it is far from even-handed.

While this is a solid piece, and Representative Markey makes his case well, he barely mentions the other Republican politicians who have repeated this lie. I understand the value of pegging this on a potential 2012 Presidential candidate, but there are over a dozen current elected officials in the Republican party who have repeated this lie as well.

Since I last updated the count a few weeks ago, eight additional Republican politicians and party organizations have repeated the lie, bringing the total to 20.

I mentioned last week that both CBS and Politico were forced to issue corrections on pieces they published citing inflated cost-estimates of a version of climate legislation that was never considered by Congress.

Despite immediate and forceful pushback from the Treasury Department, the Congressional Budget Office and environmental groups, solid reporting by the Wonk Room and the Washington Post, and thorough debunkings by Media Matters and Politifact, several leading GOP elected officials have begun citing the highly misleading figure.
