A group of 18 Republican senators have called for a probe into murky circumstances surrounding the State Department’s handling of its Iran envoy’s security clearance investigation. 

Spearheaded by Senator Bill Hagerty (R-TN), the group sent a letter to the State Department’s internal watchdog calling for investigation into the suspension of senior diplomat Robert Malley’s security clearance. 

“We write to request that the Office of the Inspector General (OIG) conduct an independent investigation into whether State Department officials complied with all appropriate laws and regulations—including policies and procedures described in the State Department’s Foreign Affairs Manual,” read the letter.

Congress was kept in the dark about the developments and was only informed about it when his replacement was announced. Malley’s suspension was first reported by Iran International June 29, and formally announced the following day by Matthew Miller, the spokesperson for the US State Department, calling it "a leave of absence”, adding that his duties would be temporarily assumed by his deputy, Abram Paley. However, it is believed he had been suspended as early as April.

Michael McCaul (R-TX), the chairman of the House of Representatives committee on foreign affairs, wrote to Secretary of State Antony Blinken on June 30 seeking "a full and transparent accounting" about why Malley was suspended and was under investigation. The Senior Republican lawmaker slammed the responseas "absolutely unacceptable"

"The Department is not in a position to provide further documents or information related to this personnel-security clearance matter," according to a copy of the correspondence.McCaul said, "Congress deserves to know exactly why the US Special Envoy (for) Iran had his security clearance suspended, was then suspended from his position, and now, according to news reports, is being investigated by the FBI," adding that he would ask the agency for a classified briefing next week.

In their letter to Diana Shaw, the acting inspector general of the Department of State, the senators outlined specific questions that must be answered “no later than Friday, July 21, 2023.”

The senators' questions mainly focused on details such as the exact date Malley’s unpaid leave started and when his security clearance was suspended or when or whether he has turned in all “Department-issued credentials that provide logical or physical access to classified systems or designated classified spaces/facilities." 

Several of their questions also pertained to the works of the State Department’s Iran Action Group, given that the Special Envoy is tasked with leading the taskforce. “After the State Department suspended Special Envoy Malley’s clearance, when and how were members of the Iran Action Group expressly directed not to discuss or otherwise share any classified information with Malley?” they asked. 

Capitol Hill Republicans are growing increasingly frustrated with the Biden administration’s unwillingness to share information about the issue. Adding salt to the injury, an article by Tehran Times, a publication controlled by the Iranian regime, provided astonishing details about Malley's situation. This has led to concerns that the Iranian government knows more about the issue than US lawmakers. 

“You would think the administration would proactively inform Congress that the person in charge of this doesn’t have the clearances to do their job, and that never happened,” said Sen. Marco Rubio (R-FL), one of the signatories of the letter and the top Republican on the Senate Intelligence Committee. “It’s not good.”

Speaking to Iran International’s Arash Alaei this week, Senator Josh Hawley (R-MO) criticized the government for not being forthcoming. He said, "You have a totalitarian regime publishing all this information and knowing it, yet your own government won't be honest with us about it." 

He further stated, "It's ridiculous...I feel like I've been lied to... They (the administration) lie to us all the time on various issues, including Afghanistan, Iraq, Iran, China... It's a pattern in this administration."

Republicans and some Democrats have been opposed to President Joe Biden's policy of negotiating with the Islamic Republic to revive the 2015 JCPOA agreement that former President Donald Trump abandoned in 2018. The talks came to a deadlock in September 2022, after 18 months of multilateral diplomacy.

Now with only about one year left from Biden’s first term, even Iran’s allies are not optimistic of resuscitating the comatose accord, with Russian Foreign Minister Sergey Lavrov saying Thursday, "I doubt it would be very realistic to expect this (revival of the JCPOA), with a new administration coming to power in the United States in a year’s time.”

"Who knows whether that administration will be Democratic or Republican. And nobody can guarantee that this new administration would refrain from using the trick of withdrawing from the agreement again," he added.
