Despite the tensions on policy issues, Trump on Wednesday gave a warm welcome to Erdogan.
It was in sharp contrast to anger in the U.S. Congress over Ankara's offensive into Syria to drive out a Kurdish militia that has been Washington's main partner in the fight against Islamic State.
Trump championed Erdogan's relationship with the Kurds.
"I think the president has a great relationship with the Kurds.
Many Kurds live currently in Turkey, and they're happy and they're taken care of, including health care," Trump said.
The two countries, which boast the two largest armies in NATO, hit a crisis point last month when Erdogan began his cross-border incursion against America's Kurdish allies in Syria and upended the U.S. presence there.
