In a letter sent Friday to the Speaker of the House John Boehner, President Obama notified Congress: "Certain US forces were recently deployed to Jordan solely to participate in a training exercise. This exercise ended on June 20, 2013. At the request of the Government of Jordan, a combat-equipped detachment of approximately 700 of these forces remained in Jordan after the conclusion of the exercise to join other US forces already in Jordan." This detachment includes Patriot missile systems, fighter aircraft, and related support, command, control, and communications personnel and systems. The detachment will remain in Jordan, in full coordination with the Government of Jordan, until the security situation becomes such that it is no longer needed.
