President Donald Trump said on Wednesday an unnamed foreign leader told him at the United Nations last week that the country would soon announce plans to build or expand five automobile industry factories in the United States.

"I just left the United Nations last week and I was told by one of the most powerful leaders of the world that they are going to be announcing in the not too distant future five major factories in the United States, between increasing and new, five," Trump said in a speech on tax reform in Indianapolis. He added the factories were in the automotive industry.

Trump did not name the country or its leader. The White House did not immediately respond to a request for comment.
