NBA player Enes Kanter arrived back in the U.S. having been detained in Romania, where authorities declared his passport cancelled by his native Turkey.

The center for the Oklahoma City Thunder is an outspoken critic of Turkey’s Islamist President Recep Tayyip Erdogan.

In a video made at the airport in Bucharest, Kanter said after hours of detention, “You know the reason behind it is because of my political views and the guy who did it is Recep Tayyip, the president of Turkey. You guys know him … He attacked people in Washington. He’s a bad, bad man. He’s the dictator and the Hitler of our century.”

Kanter was referring to the violent attack on peaceful protesters in front of the residence of the Turkish ambassador in Washington by Erdogan supporters. Victims of the attack — comprised of Kurds, Armenians, Greeks and Yazidis who have borne the brunt of the Turkish state’s oppressive policies against minorities — said the attackers were not ordinary civilians, but people with military training, “likely from Recep Tayyip Erdogan’s security detail.”

Kanter has been a vocal critic of Erdogan and an avid supporter of Erdogan’s nemesis Fethullah Gulen, a powerful Turkish cleric in America who Erdogan says was behind the July 2016 failed coup that attempted to oust the Turkish leader.

Kanter, who posted his message also in Turkish, was flown out the London after close to five hours due to the efforts of the State Department. From there, he was flown to New York.

Kanter’s family in Turkey has disowned him after Kanter came out in support of Gulen, a stance which earned him messages in Turkey containing death threats sent with images of guns and nooses.

Posting from the airport in Bucharest, Enes tweeted a picture of himself with the airport officials assigned to watch him:
