That's simply a lie.
Congress has tried to change the "natural born Citizen" requirement, many times in recent years, to include those "citizens" born in foreign countries to be eligible. Their efforts have failed.
One example:

Published: Washington, D.C. : U.S. G.P.O. : 2000.
This show that Congress knows full well that "citizens" who are born in a foreign country are not "natural born Citizens," else there would be zero need for their efforts such as this.
