Iran’s ambassador to the International Atomic Energy Agency (IAEA) said the nuclear inspection organization is barred from revealing to the United States any details of deals it has inked with Tehran to inspect its contested nuclear program going forward, according to regional reports.

Recent disclosures by Iran indicate that the recently inked nuclear accord includes a series of side deals on critical inspections regimes that are neither public nor subject to review by the United States.

Reza Najafi, Iran’s ambassador and permanent envoy to the IAEA, stated over the weekend that no country is permitted to know the details of future inspections conducted by the IAEA. In addition, no U.S. inspectors will be permitted to enter Iran’s nuclear sites.

"The provisions of a deal to which the IAEA and a second country are parties are confidential and should not be divulged to any third country, and as Mr. Kerry discussed it in the Congress, even the U.S. government had not been informed about the deal between IAEA and Iran," Najafi was quoted as saying by Iran’s Mehr News Agency.

Due to the secretive nature of these agreements, IAEA officials vising with lawmakers are barred from revealing to them the details of future inspections.

The revelation has rattled lawmakers on Capitol Hill, several of whom are now rallying colleagues to sign a letter to President Barack Obama protesting these so-called side deals.

Rep. Mike Pompeo (R., Kansas) and at least 35 other lawmakers are circulating a letter to Obama to provide Congress the text of these agreements as is required under U.S. law.

"It has come to our attention that during the recent negotiation of the Joint Comprehensive Plan of Action (JCPOA) with Iran, at least two side deals were made between the International Atomic Energy Agency (IAEA) and Iran," the letter states, according to a copy obtained by the Washington Free Beacon.

"These side deals, concerning the ‘roadmap for the clarification of past and present outstanding issues regarding Iran’s nuclear programs,’ have not been made available to the United States Congress," it states. "One deal covers the Parchin military complex and the other covers possible military dimensions (PMDs) of Iran's nuclear program."

An informational email being circulated to lawmakers explains, "according to the International Atomic Energy Agency (IAEA) and the Obama Administration, these agreements have been negotiated in secret between the IAEA and Iran."

Secretary of State John Kerry has personally "stated he has not seen these agreements and the Administration failed to submit these agreements as part of the JPCOA," the email states.

Under the terms of a bill meant to give Congress a final say over the deal, the Obama administration is required to provide text of all agreements, the lawmakers write to Obama.

"Under the clear language of the Iran Nuclear Agreement Review Act, which you signed into law, members of Congress are entitled to the text of these two side deals," it states. "Specifically, members have a right to all ‘annexes, appendices, codicils, side agreements, implementing materials, documents, and guidance, technical or other understandings and any related agreements, whether entered into or implemented prior to the agreement or to be entered into or implemented in the future.’"

"Congress’s legal right to these documents creates a corresponding legal obligation for your administration to provide them for our review," the letter says.

The lawmakers are demanding that the White House "immediately secure" these documents from IAEA "and then provide them to Congress" for review.

Pompeo and Sen. Tom Cotton (R., Ark.) sent a separate letter to Obama administration official last week asking for them to disclose the nature of all secret side agreements with Iran.

Iran’s IAEA ambassador claims the agreements with the IAEA are separate from the actual nuclear accord inked with global powers.

"The Agency would know the nature of confidential documents and Iran have clearly briefed the IAEA on this; we have agreed on implementation of a roadmap which is not a part of the JCPOA, with the implementation already on process even before the Congress could examine and approve the deal," Najafi was quoted as saying.

One senior congressional source familiar with the effort to obtain further information about the deal told the Free Beacon the Obama administration is not being transparent in the review process.

"On top of all the concessions–from ballistic missiles to conventional arms to a 24-day inspection period–we now learn that additional side deals were struck between the IAEA and Iran," said a senior congressional source familiar with the effort to obtain further information about the deal.

"The Administration promised a transparent review process that would allow Americans and their elected representatives to assess the deal for themselves, but as it turns out, that was just utter bullsh**," the source added. "The Administration signed off on an agreement that included a series of Iranian Eastern eggs, including secret deals regarding the possible military dimensions of Tehran's nuclear program, to which Congress and the public are not privy."
