"Section 3610 of the [CARES] Act authorizes agencies to reimburse contractors for the cost of paid leave incurred to keep contractor or subcontractor personnel in a 'ready state' to the extent that the personnel were [1] unable to access a government-approved facility, and [2] unable to telework because their jobs could not be performed remotely.... DOD issued a class deviation  ... that provides a framework for contracting officers to authorize payment of paid leave (including sick leave) costs resulting from the COVID-19 crisis.... NASA issued a general FAQ document geared towards helping contractors understand the agency's response to COVID-19.... ODNI released a short memorandum emphasizing its desire for the Intelligence Community to apply Section 3610 'to the greatest extent possible.' "
