Yep.  She got duped  in pursuit of her own political ends.   Or maybe she knew the Assad people  were paying for her trip and chose not to disclose because of the firestorm that would ensue .  Maybe she went anyway thinking nobody would notice.  Now that they have she wants to pay for it.  CYA.  In any case, meeting with Assad shows she has no moral of ethical fiber.  Not to mention common sense.
