His Soros Fellowship was not George Soros’s, but rather endowed by older brother Paul and wife Daisy. Paul's wiki states the fellowship is for talented, accomplished immigrants or children of immigrants who have been associated with organizations dedicated the ideals of the US Bill of Rights. I know little of Paul, perhaps he twists words as well as his notorious younger brother, and wiki is far from a conservative benchmark, but it’s not superficially damning.
He declined the WEF title of "Young Global Leader" and took WEF to court to have his name removed from their listing.
IIRC his parents naturalized before his birth, making him a Natural Born Citizen by all but most stringent of the array of disputed definitions of that term, those that require grandparents have been citizens. Which as Cruz pointed out, could disqualify Trump. I can’t resolve that definitional dispute but would love a Justice Thomas written SCOTUS decision to settle it. Obama proved the Framer’s wisdom in including the term, but legal uncertainty in its precise meaning is counterproductive. Outside the "Natural Born" subset Vivek supports general citizenship for children of legal immigrants, but not for children of illegals, which IIRC does NOT make him a hypocrite on the subject.
Conservatives have often been fooled and burned by alleged converts. Checking backstories is important to avoid that. Yet true conversions are not rare and include many greats, amongst them President Reagan. They are valuable and their conversion experiences may help others covert. We should apply his method, "Trust but verify."
I will have to re-check that link I provided. But there are many others reporting the same information, including video of him. Regarding his parents, why don’t you provide a link please, because I sure could not find one. The only references I have or that his parents Were Indians from India without mentioning their legal or illegal immigration status, etc. Any thoughts on his other points?
