"So while I appreciate President Erdoğan showing us the information, we don't know the origins, we don't know — and it was very much a propaganda video," Ernst added. Graham, asked if Erdoğan showed them a "propaganda" video, confirmed that he did. "He showed a video about the history of PKK terrorist attacks ... and what I told him is I'm not here to retry the past. I acknowledge that you have a legitimate national security concern. ... Do you want me to get the Kurds to play a video about what your forces have done? So I was very firm," Graham added.

Axios first reported that Erdoğan showed senators the video.

The meeting follows heightened tensions between Capitol Hill and Turkey, in the wake of Trump's decision to pull back U.S. troops and Turkey's subsequent military invasion against Kurdish-led YPG forces, which Turkey also claims is a terrorist group tied to the PKK. The U.S. does not consider the YPG a terrorist organization, however, and has worked closely with their forces in the fight against ISIS.

Senators have offered multiple sanctions bills to slap new financial penalties on Ankara over the incursion. The House previously passed its own legislation, but sanctions talk stalled in the Senate amid Erdoğan's visit.
