>Everyone assumes she not only is a citizen
Wouldn't marrying a U.S. citizen (especially a Senator) kind of take care of that? I know they have to be married for a while, but they were married for years.
I do not know, but no one has said that. It would be important to find out how and when she became a citizen. The "if" question would be far out, but it is not the reason for determinming one and two.
You do not automatically become an American citizen by marrying an American. My hubby is from England...in fact, he was not a citizen while he fought for this country in Viet Nam...and received two very real Purple Hearts while in combat. Upon returning he went through the process to become a citizen and we proudly watched his swearing in at Camp Lejune, NC in 1970.
