John Kerry is in the hot seat after new reports revealed that former President Obama’s Secretary of State was actively working with his Iranian counterparts to keep the Iran Nuclear Deal in place.

The Boston Globe reported Friday that Kerry has been secretly meeting with politicians and diplomats around the world in an attempt to salvage the future of the Iran nuclear deal and undermine the current administration.

According to The Globe, Kerry met with Iranian Foreign Minister Javad Zarif multiple times over the last few months. He also met with German President Frank-Walter Steinmeier, French President Emmanuel Macron and multiple members of Congress here in the United States.

According to Fox News political reporter Brooke Singman, a Kerry spokesperson admitted the reports were accurate, telling the news outlet that “Secretary Kerry stays in touch with his former counterparts around the world,” and that Kerry was working to make sure the tenants of the Iran Deal “remain effective.”

The report comes as the Trump administration is under intense scrutiny for allegations that they colluded with a foreign power to swing the presidential election. No evidence has yet been presented to support that claim.

Legal scholar Alan Dershowitz says Kerry is in clear violation of the Logan Act.

The Logan Act states:

Any citizen of the United States, wherever he may be, who, without authority of the United States, directly or indirectly commences or carries on any correspondence or intercourse with any foreign government or any officer or agent thereof, with intent to influence the measures or conduct of any foreign government or of any officer or agent thereof, in relation to any disputes or controversies with the United States, or to defeat the measures of the United States, shall be fined under this title or imprisoned not more than three years, or both.

The Boston Herald has called for a full investigation into Kerry’s actions:

If special counsel Bob Mueller is truly interested in investigating people who are colluding with nefarious foreign powers to undermine U.S. interests, John Kerry should be Target No. 1 for secretly meeting with Iran’s foreign minister, Javad Zarif, and other foreign officials in recent weeks to usurp U.S foreign policy. It’s a role that as a private citizen, Kerry has no mandate or authority to pursue.

President Trump attacked Kerry’s actions on Twitter, saying Monday. “The United States does not need John Kerry’s possibly illegal Shadow Diplomacy on the very badly negotiated Iran Deal. He was the one that created this MESS in the first place!”
