The government can monitor your conversations with your lawyer.
The 6th amendment grants us the right to legal representation. Much of this has changed. In addition to being detained without a charge, hundreds of US residents have been denied access to the advice of an attorney. The Bush Administration in particular has filed several papers to argue that Americans held in military prisons without charge should be denied access on the grounds that it would interfere with the interrogation process. For those who are able to get through to their attorney, the government also has access to monitor private conversations between a defendant and their attorney in federal jails.
