U.S. President Donald Trump is expected to endorse the potential sale of F-35 fighter jets to Türkiye and tell President Recep Tayyip Erdoğan he's prepared to restore Ankara's access to the multinational program building the warplane, reports said Tuesday.

The move ⁠would be the biggest gesture yet from Trump – who is traveling to Ankara to attend a NATO summit – to Erdoğan, whom he regularly praises and sees as a close ally. The two countries have enjoyed warmer ties since Trump returned ​to office last year.

U.S. in 2020 imposed sanctions and removed Türkiye from the F-35 stealth fighter jet program, where Ankara was also a production partner, following its purchase of Russian ​S-400 ⁠air defense system.

Washington claimed the system would endanger the jets and is inoperable with NATO systems, while Ankara repeatedly said there is no conflict between the two and proposed a commission to study the issue. Türkiye also said it fulfilled its obligations on the F-35s and that its suspension broke the rules.

Ankara maintains that the jets would strengthen not only Türkiye, but also NATO.
