ABC News’ Annie Allen, Dave Strickland, Gina Sunseri and Tahman Bradley report:
Former First Lady Barbara Bush will not be leaving the hospital today, ABC News has learned.
On Wednesday morning, spokesman Jim McGrath said the former First Lady had "a procedure" overnight. He would not elaborate but doctors will give him a statement on her condition which will be released shortly.
Bush was rushed to Houston’s Methodist Hospital on Tuesday evening, where she was undergoing tests for abdominal pains, a staffer for former President George H.W. Bush told ABC News.
The Bush spokesman told ABC News that all of the tests have come back negative, but did not say what doctors were testing for. Methodist Hospital sources say that Mrs. Bush’s condition is not life threatening.
The former first lady arrived at the hospital around 5:30 p.m. CT.
Former President Bush is at the hospital with his wife. The former first couple have a home in Houston.
