Why Was Congressman Weldon Denied Access to Terri Schiavo?

First the media was denied access to Terri. Now Congressman Weldon (according to his statement a few minutes ago). Why? If Terri is truly in a "persistent vegetative state" as is claimed by her husband (who had children with another woman while married to her) and his lawyer, why were the media and Rep Weldon denied access? If either the media or Rep Weldon were given access, they would be able to see for their own eyes whether or not she is in a "PVS." Since Michael has said she is in a "PVS," granting them access would only HELP Michael Schiavo's case in such circumstances...
