"Stuck at the border or not; it is not our problem".
The US citizen, named by Turkish media as Muhammed Darwis and believed to be of Jordanian descent, has spent two days in the middle of a battle of wills between the countries who are both refusing to allow him entry.
A US State Department official said it was "aware of reports of the detainment of a US citizen by Turkish authorities", but could not comment further because of privacy rules.
After welcoming Turkish President Recep Tayyip Erdogan on the opening day of public impeachment hearings for a second visit to the Oval Office, President Trump did something highly unusual for such encounters: he invited a select group of Republican senators to join the two leaders' meeting.
Many of those held are foreign fighters.
Despite those objections, Trump approved Erdogan's visit after the Turkish government agreed to a US -brokered cease-fire deal that cemented a Kurdish withdrawal from certain areas of northern Syria. Of those, 19 have returned - 15 men and four women - and 13 have been charged.
In the Senate, two Democrats introduced legislation denouncing Turkey's targeting of journalists, political opponents, dissidents, minorities and others.
Former Dick Cheney National Security Adviser John Hannah discusses the contentious Syria situation and the increased death toll in Iraq since October 1. Erdogan sees Kurdish forces in Syria as an extension of a separatist Kurdish group that's been fighting inside Turkey since the 1980s.
Who else has Turkey deported?
Turkey has criticised Western countries for not taking back captured members of the Islamic State of Iraq and the Levant (ISIL or ISIS). Danish authorities said their citizen had been arrested on arrival in Copenhagen.
"Efforts to identify the nationalities of foreign fighters captured in Syria have been completed, with their interrogations 90% finished and the relevant countries notified", Çataklı said, according to state-owned Anadolu news agency.
Turkey has not confirmed whether those being repatriated were seized in Syria, or in Turkish territory.
But Erdogan claims the Kurds have not vacated border areas and says he will give Trump a list of attacks carried out by Mazloum Abdi, the commander of the US -backed Syrian Kurdish-led force.
The Turkish president said counterterrorism, especially security issues of common concern, military and defense industry cooperation, as well as economic and commercial relations will also be addressed.
Why is Turkey deporting people?.
The UK is said to have withdrawn citizenship from more than 100 people - among them the IS recruit Shamima Begum, who left London as a teenager. "Whether they take them or not, it is not our problem". "Let someone else fight over this long-bloodstained sand (Syria)", he said at a White House news briefing.
The meeting is expected to cover bilateral relations and foreign policy issues, including Syria.
How will the repatriations work?"And Turkey has some support in global law to demand that sender states take their citizens back", he said.
Under the 10-point agreement, Turkey will retain control of the area it seized during the offensive it launched on Oct 9, which was green-lighted by President Donald Trump when he ordered U.S. troops to pull back.
