If a state, territory and the District of Columbia is using other money to provide individuals with an amount higher than $300, is there something that limits to only contributing $100 or may the state/territory provide additional money?

The Presidential Memorandum authorized up to $400 through the supplemental lost wages assistance program, including a $300 federal contribution. If the state, territory and the District of Columbia chooses to provide an amount beyond this using non-UI funds, it is considered a separate state/territory program which would be subject to authorization under state law.
