The Trump administration has made drastic changes to the federal government since taking power in January, including restructuring the government and rooting out wasteful government spending, which includes canceling grants.

Attorneys general from Democratic-led states said the federal government is using obscure rule to slash previously awarded funds.

Democratic state attorneys general filed a lawsuit on Tuesday asking a judge to declare that a key tool Republican President Donald Trump's administration has relied on to cancel federal grants is being used unlawfully to slash billions of dollars in funding.
