Rob Malley, the US envoy to Iran, plans to present a report on the Vienna talks tonight (Tuesday) in a closed-door congressional session.
Rob Malley, Washington's envoy to Iran, and Brett McGurk, the White House's coordinator for the Middle East and North Africa, also reportedly plan to report on Iran in private.
The meeting comes as some members of Congress are trying to block any attempt to block US President Joe Biden's government from reaching an agreement with Iran.
