On January 21, the President issued a Memorandum to Extend Federal Support to Governors’ Use of the National Guard to Respond to COVID-19 and to Increase Reimbursement and Other Assistance Provided to States. The memorandum provides a 100 percent federal cost share for all work eligible for assistance under Public Assistance Category B, pursuant to the Stafford Act, performed from January 21, 2021 through September 30, 2021.

Yesterday, the President issued a Memorandum on Maximizing Assistance from the Federal Emergency Management Agency, which provides that the 100 percent cost share is retroactive for eligible work performed from January 20, 2020 through January 20, 2021.
