The Obama administration stopped fighting a Freedom of Information Act (FOIA) request Friday and released documents showing that NASA Goddard Institute for Space Studies Chief James Hansen was paid $250 an hour by a Canadian law firm for advice and testimony against developing Alberta’s oil sands, income which Hansen does not appear to have disclosed.

Hansen was arrested outside the White House once this August, and again Sunday, while protesting the Keystone XL pipeline, which will carry Alberta’s oil south to the United States.
