The Washington Examiner is reporting Obama For America is about to get rocked by a scandal involving taxes and foreign donors.

According to knowledgeable sources, a national magazine and a national web site are preparing a blockbuster donor scandal story.

Sources told Secrets that the Obama campaign has been trying to block the story. But a key source said it plans to publish the story Friday or, more likely, Monday.

According to the sources, a taxpayer watchdog group conducted a nine-month investigation into presidential and congressional fundraising and has uncovered thousands of cases of credit card solicitations and donations to Obama and Capitol Hill, allegedly from unsecure accounts, and many from overseas. That might be a violation of federal election laws.
