"We accompanied our president on his visit to Washington, which is very important for Turkey-USA ties".
Five Republican senators, including vocal Turkey critic Lindsey Graham, came to the White House and spoke with Erdogan and Trump about the F-35 programme.
A USA citizen suspected of being a member of ISIS is reportedly stuck in a heavily militarized no-man's land between the borders of the country that kicked him out, Turkey, and the one that refuses to accept him, Greece, officials say.
Trump, at Wednesday's news conference, made no reference to that, hailing Turkey as a great North Atlantic Treaty Organisation partner.
"Instead, we should suspend Turkey from North Atlantic Treaty Organisation for engaging in ethnic cleansing and other atrocities in Syria, prompting more than 180,000 civilians to flee".
He said that he and Turkey's president have been "very good friends" for a long time and understand each other's country.
Turkey, which has suffered multiple deadly attacks by IS militants, says it has captured 287 fighters in northeast Syria since launching a cross-border incursion on Oct 9 targeting the Kurdish YPG militia.
Mr Trump ordered USA troops stationed in the border area to withdraw ahead of the Turkish invasion while exhorting Mr Erdogan in an extraordinarily undiplomatic letter to avoid too much bloodshed.
The average sentence for fighters returning to European countries has been about five years of imprisonment, which generates serious domestic security threats if the returned European nationals can not go through an efficient rehabilitation process.
"While the F-35s are never completely off the table, Erdogan will have to give up his procurement plans involving Russian equipment if he wants back into the 'F-35" club that so many nations are now a part of.
The letter cited Erdoğan being "closer" to Russian President Vladimir Putin, including purchasing the S-400 air-missile defense system instead of the F-35 fighter jets from the United States, and his taking other steps antithetical to USA interests.
"As such, talking to Turkey remains crucial, although the pressure on democracy and human rights should also remain significant".
Asked to comment on the reports on Tuesday, Erdoğan said: "Whether [the deported Isis fighters] are stuck there at the border it doesn't concern us".
A Turkish interior ministry spokesperson told local media outlets on Monday that a United States and a Danish national were deported from Turkey.
Such a move could endanger Turkey's membership in the US -led North Atlantic Treaty Organisation defense alliance.
