WNBA star Brittney Griner is back in the U.S. after being held for nine months in Russia. The 32-year-old Phoenix Mercury center arrived in San Antonio, Texas early this morning. She's now at the Brooke Army Medical Center in San Antonio, where the government often sends people who need to be debriefed or who require sensitive medical care after going through an ordeal like Griner's time in Russian custody. She was exchanged for Russian arms dealer Viktor Bout on Thursday.
