Sierra Club president Michael Brune said last week that he stopped his organization's acceptance of donations from a gas-drilling company when he found out about them.
Turns out that his chronology might be off.
"In 2010, soon after I became the organization's executive director, I learned that beginning in 2007 the Sierra Club had received more than $26 million from individuals or subsidiaries of Chesapeake Energy, one of the country's largest natural gas companies," Brune wrote in his "Coming Clean" blog.
