We are especially grateful to everyone at Johns Hopkins who worked to make David's recovery possible. Now it is important that our time and energy be focused on David's recovery. David is in good condition and continuing to recover more and more every day. We are asking the media to please respect our privacy during this time of healing. Thanks for your understanding."
