Secretary of State Marco Rubio is scheduled to testify before Congress for the first time since the Iran war began on February 28, appearing in back-to-back hearings on Capitol Hill to address the administration's diplomatic efforts worldwide.

Rubio will appear before the Senate Foreign Relations Committee and House Appropriations subcommittee on Tuesday to present the State Department's annual budget request. He is expected to return Wednesday for additional testimony before the House Foreign Affairs Committee and Senate Appropriations subcommittee.

The hearings come amid questions about the administration's handling of the Iran conflict, which began despite previous promises to avoid prolonged Middle East engagements. The ceasefire between Washington and Tehran has faced recent challenges from ongoing attacks between the parties.

Congress has shown growing resistance to the conflict, with the Senate advancing legislation last month that would force withdrawal from Iran after GOP Senator Bill Cassidy joined Democrats in supporting the measure following his primary election loss. The House had planned a similar war powers vote, but Republican leadership prevented it from reaching the floor when it became clear the majority party lacked sufficient support to defeat it.

Rubio previously participated in a classified briefing for lawmakers shortly after the initial U.S. and Israeli strikes against Iran. During that session, he faced criticism from Democrats over the lack of congressional approval while receiving support from most Republicans for action against Iran.

The Secretary of State is also expected to face questions about the administration's approach toward Cuba, as President Trump has suggested the island nation could be a future target after Iran operations conclude. The administration recently announced criminal charges against former Cuban President Raúl Castro amid renewed threats against Cuba's government.
