Other than obvious forged long form, short form, and selective service forms, and the pre-owned like new social security card, there is no evidence he was ever a citizen of the USA. Forget natural born. No evidence he was ever a citizen.
Probably born in an unwed mothers home in Vancouver, Canada, to a teen too young to confer her citizenship upon him, meant to be given up for adoption, but she took him at the last minute.
As a US Senator he was handed a ceremonial passport. First USA pass he ever had. Based on zero documentation, and one guy died in the passport office break in to obfuscate his lack of documentation.
Total supposition.
He was born in KENYA. The “footprint” birth certificate proves it.
