From the article linked at the top of the thread:

“I don’t think American elections should be bankrolled by America’s most powerful interests or, worse, by foreign entities,” Obama continued. “They should be decided by the American people. And I urge Democrats and Republicans to pass a bill that helps correct some of these problems.”

IIRC the credit card donation page on Obama’s campaign website had several information fields de activated and there was quite a question about untracked foreign donations making their way in.

Maybe some other lizards have a better recollection of this than I.
