Who forgot to tell Joe not to mention the list?

They forgot to give him the list of things to not say that had that on it.
Harris was born in the USA to parents both of whom were temporary visiting aliens at the time of her birth. Harris was born with equal citizenships in three countries and raised during the most influential period of her childhood in an foreign land, thus her natural allegiance is not solely with the USA, but is equally split among at least three different countries.
Harris is merely a born citizen by statute (statutory born citizen), not the more restrictive natural born Citizen as required by the Constitution (not that dems care about a little thing called the Constitution). Harris is Constitutionally ineligible to become president or vice president.
However, the Constitution isn't worth the parchment it was written on if we don't have the courage to enforce it. The Founders would be appalled.
