(CNN) The Trump administration has formally withdrawn its offer for Turkey to purchase a Patriot missile system in retaliation for Turkey's receipt of the Russian-made S-400 missile system.

"We have consistently told Turkey that our latest offer of PATRIOT would be withdrawn if it took delivery of the S-400 system. Our PATRIOT offer has expired," a US State Department official tells CNN.

In December, the US State Department announced that it had approved the possible sale of a $3.5 billion Patriot missile system to Turkey.

The withdrawal of the Patriot missile defense system is just the latest US response to Turkey's acquisition of the S-400 system.

The US has also ejected Turkey from the F-35 jet program, preventing Turkey from acquiring some 100 of the stealth jets and removing Turkish companies from the production chain.
