He’s as much an American citizen as my children who were born in the United States of a forgein born mother. And he can run for President, or be selected as Vice President and your interpretation of the issue is not going to change that.
We’re not discussing citizenship when the subject is ‘natural born citizen’.
Three types of citizenship are recognized by our government: native born; naturalized; and citizen-by-statute. All have equal rights. All can serve in Congress, either as a Representative in the House, or as a Senator in the Senate.
The following link will take you to the government’s own Immigration Service web page describing the three types of citizenship.

Natural Born Citizen is NOT a type of statutory citizenship as per the Federal Government. Natural Born is ONLY an eligibility requirement for the U.S. Presidency per Article II, Section 1, clause 5, of the U.S. Constitution, and requires, as per the Founders, the President to be born in the United States (jus solis) AND of citizen parents (jus sanguinas).
No one has the RIGHT to be President. The eligibility requirement of Natural Born Citizenship (jus solis + jus sanguinas: born in the U.S. of U.S. citizen parents) must be viewed as a means to prevent split allegiance for any President of the United States.
