Kamala Harris is a natural-born US citizen, as indicated that she was born in the State of California and was sworn in as Vice President without objection on Jamuary 20, 2021.
There is ZERO chance that any Court will overturn the Obama precedent (British subject at birth), and I would be astonished if any US court would even hear such a case.
Kamala is an anchor baby. Neither of her parents were US citizens at the time of her birth. Just because Obama slipped through the crack does not mean Harris will.
Well, Biden just dropped out and endorsed Kamala so we will soon find out.
