Regretably, since the vehicle is in your 'friends' name, she will be stuck with all 'damages' that the rental agency suffers... up to and including the total value of the car or loss of rental income.
There are at least 17 lawsuits (!!) filed in various courts, including the US Supreme Court, asking if Obama is a natural born citizen (as req'd by Art II, Sec 1 of the US Constitution).
Why has he spent over $1.7M in legal fees to block disclosure... rather than spend $12 for a VALID birth cert to settle the matter? The 'certificate' he has presented doesn't qualify to get a drivers license, wouldn't allow a child to qualify for Little League, or for a real citizen to get a US passport!
