Richard Pollock of the Daily Caller documents facts about the U.S. secretary of state that could prove embarrassing for Obama administration advocates who target “tax havens.”

Secretary of State John Kerry and his wife Teresa Heinz have invested millions of U.S. dollars through family trusts in at least 11 offshore tax havens, according to The Daily Caller News Foundation’s Investigative Group.

The revelation comes on the heels of the release of the Panama Papers, a treasure trove of 11.5 million legal and financial records documenting how some of the world’s richest and most powerful people have used offshore bank accounts to conceal their wealth and avoid taxes.

Since the release of the papers, no American politician has been identified as using the secretive offshore accounts.

But a DCNF investigation has confirmed that the former Massachusetts Democratic senator and his billionaire wife, using an elaborate set of Heinz family trusts, have invested “more than $1 million” each into 11 separate offshore accounts — mainly hedge funds in the Cayman Islands.

The investments were made during both Kerry’s tenure in the Senate and in his present position as the nation’s chief diplomat.
