U.S. President Joe Biden's top aides are heading to the Middle East to discuss a Gaza ceasefire, hostage deal, and the transition in Syria. Secretary of State Antony Blinken will visit Jordan and Turkey, while national security adviser Jake Sullivan will make stops in Israel, Qatar, and Egypt. The visit could shape Biden's legacy in the region before former President Donald Trump returns to the White House. The future of Syria and progress towards a deal to end the war in Gaza will be key topics of discussion.
