No Person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State for which he shall be chosen. [U.S. Constitution, Article I, section 3, clause 3]
Now unless you have something to prove he wasn’t a US citizen for at least 9 years and an inhabitant of Texas, then try again.
Proof and Truth are not something the tRumpster are good at, nor do they care about it. It is whatever they say it is.
Where's the CRBA? If he doesn't have one...he's a Canadian...or a citizen of nowhere since he renounced.
