Senator Lindsey Graham told 124NEWS that Congress will oppose the F-35 sale amid concerns Russia could gain access to the advanced fighter jet's technology through Turkey

The claim attributed to Lindsey Graham is consistent with the long-standing position of many members of the U.S. Congress, although I could not independently verify the specific "124NEWS" interview.

What Senator Graham reportedly argued

According to the reported statement:

Congress is expected to oppose any sale of F-35 fighter jets to Turkey.

The main concern is that Turkey still possesses the Russian-made S-400 air-defense system.

U.S. lawmakers fear that the S-400 could collect electronic data on the F-35's stealth characteristics, and that Russia could ultimately gain insights into the aircraft's technology. This has been the central reason Turkey was removed from the F-35 program in 2019–2020. 

Why this matters

The F-35 is the United States' most advanced stealth fighter. American officials have long argued that operating it alongside the Russian S-400 creates security risks because:

The S-400 may record information about the F-35's radar signature and flight characteristics.

Any compromise of that data could reduce the aircraft's military advantage.

Congress has previously required Turkey to give up the S-400 before it can rejoin the F-35 program. 

Current political situation

Although President Donald Trump recently said he is willing to consider restoring Turkey's access to the F-35 program, many Republican and Democratic lawmakers remain opposed unless the S-400 issue is fully resolved. Several senators have publicly reiterated that Congress is unlikely to approve an F-35 sale while Turkey retains the Russian system. 

Bottom line: The reported statement aligns with Congress's established national security concerns. However, I could not confirm that the exact wording came from a verified interview with "124NEWS"; the broader position itself is well supported by recent reporting.
