Former first lady Barbara Bush is in a Houston hospital after complaining of a "little bit of pain." Family spokesman Jim McGrath said Mrs. Bush went to Methodist Hospital about 6 p.m. Tuesday as a precaution. She had been experiencing some pain this week but McGrath did not know what it was. McGrath said all of the results for tests she had undergone had been negative. Mrs. Bush may be released later Tuesday or could be held overnight as a precaution. McGrath said former President George H.W. Bush is with her. Mrs. Bush is 83.
