To direct the Administrator of the Federal Emergency Management Agency to transfer certain amounts to the Disaster Relief Fund.

HR 10143 requires the FEMA Administrator to transfer unspent funds from COVID-19 relief acts and funds that have passed their initial performance period for past disaster declarations into the Disaster Relief Fund. This bill directly affects FEMA's budget management by redirecting leftover government funds that were originally allocated for specific purposes. The key mechanism is a mandatory transfer of these unobligated amounts to the central Disaster Relief Fund, which is used to respond to future disasters. The bill does not create new spending but reallocates existing, unused funds to strengthen the Disaster Relief Fund's available resources.
