The hearing shall be held before the Office and shall be conducted in accordance with the rules prescribed pursuant to subsections (f) and (g) of section 1234 of this title.
Pending the outcome of any hearing under this section, the Secretary may suspend payments to a recipient, suspend the authority of the recipient to obligate Federal funds, or both, after such recipient has been given reasonable notice and an opportunity to show cause why future payments or authority to obligate Federal funds should not be suspended.
Upon review of a decision of the Office by the Secretary, the findings of fact by the Office, if supported by substantial evidence, shall be conclusive. However, the Secretary, for good cause shown, may remand the case to the Office to take further evidence, and the Office may thereupon make new or modified findings of fact and may modify its previous action. Such new or modified findings of fact shall likewise be conclusive if supported by substantial evidence.
