This week, U.S. Sen. Marco Rubio, R-Fla., a member of the U.S. Senate Foreign Relations Committee and the vice chairman of the U.S. Senate Select Committee on Intelligence, led a letter to U.S. Sec. of State Antony Blinken “requesting an update on U.S. action to hold Iran accountable for multiple violations” on the Comprehensive Plan of Action (JCPOA).

More than a dozen Senate Republicans signed the letter, including U.S. Sen. Rick Scott, R-Fla.

“In 2015, the Comprehensive Plan of Action (JCPOA) was signed by the Obama Administration, Iran, and other countries agreeing to place restrictions on Iran’s nuclear program in exchange for sanctions relief. One condition included the JCPOA tasking the International Atomic Energy Agency (IAEA) to ensure the regime in Tehran adheres to nuclear restrictions. Even with the signed agreement, Iran proves to be non-compliant and further continues nuclear programs,” Rubio’s office noted.

“The Iranian regime is intent on fomenting terror across the region, as evidenced by its proxies, Hamas and Hezbollah’s, brutal attacks this weekend on our ally, Israel. Now more than ever, you must ensure that you hold the regime accountable for its failure to comply with obligations under the Nuclear Non-Proliferation Treaty (NPT). Further, we were disappointed that the administration did not call for a formal censure of Tehran given its continued non-compliance with the IAEA,” the senators wrote Blinken.

“The Biden administration has failed to press for concrete action against Iran in Vienna. We are especially disturbed by reports that the United States led efforts to oppose a censure of Iran. As Iran violates its commitments and refuses to comply with the IAEA, your business-as-usual approach to resolving the situation is tantamount to an endorsement of the Iranian regime’s activities,” the senators added.
