Trump tweeted: "Happy birthday to the great @leegreenwood83. You and your beautiful song have made such a difference. MAKE AMERICA GREAT AGAIN!" The singer's Twitter name is @TheLeeGreenwood , but the president directed his message to a Lee Greenwood who describes himself as a New York lawyer with Washington, DC roots.
That Greenwood commented on the mistake, writing : "I get this a fair amount, but certainly not at this level."
Trump later corrected his tweet.
