(1) Disclose confidential or privileged information; or

(2) For a current OGE employee, testify as an expert or opinion witness with regard to any matter arising out of the employee's official duties or the functions of OGE unless testimony is being given on behalf of the United States (see also §2635.805 of this chapter).
