Sen. Ted Cruz is pushing to delay the start of Congress’s 60-day review period for the Obama administration’s nuclear deal with Iran.
The Texas Republicans argues the review period should not begin until after the administration hands over so-called side deals between Iran and the International Atomic Energy Agency (IAEA). 
Cruz, who is running for president, introduced a resolution on Thursday arguing that President Obama didn’t hand over all materials—including the side deals— to Congress. As a result, he said the 60-day clock shouldn’t have started to tick.
Cruz says that under the terms of the review legislation Congress overwhelmingly passed earlier this year, any “side” deals were included as parts of the deal that had to be turned over to lawmakers.
The legislation approved by Congress states: “The 60-calendar day period for review of such agreement in the Senate cannot be considered to have begun until the Majority Leader certifies that all of the materials required to be transmitted under the definition of the term ’agreement’ under such Act, including any side agreements with Iran and United States Government-issued guidance materials in relation to Iran, have been transmitted to
the Majority Leader.”
Delaying the start of the deal would give more time for opponents of the deal to pressure a handful of key Senate Democrats after they return from the August recess in September.
The two agreements between Iran and the IAEA have become a focal point of Republican opposition to the deal, as well as a point of concern for some Democrats who have suggested they want a better understanding of the deals.
The push from Cruz comes as Sen. Tom Cotton (R-Ark.) and Rep. Mike Pompeo (R-Kansas), who first raised questions about the “side” deals, wrote to Undersecretary of State Wendy Sherman and Energy Secretary Ernest Moniz on Thursday requesting the two administration officials clarify when, and if, they’ve read the two agreements between Iran and the IAEA.
While McConnell hasn’t specifically called for delaying the review period, he, as well as House Speaker John Boehner (R-Ohio), Cotton and Pompeo asked Obama to turn over the agreements earlier this month.
They said that not having them “leaves Congress blind on critical information regarding Iran’s potential path to being a nuclear power and will have detrimental consequences for the ability of members to assess the JCPOA.”
McConnell said on Thursday that he had yet to receive the documents from the White House, adding that the delay is “simply not acceptable.”
