Denise Cheung resigns after Trump appointees demand she open grand jury investigation into EPA grants

A top federal prosecutor has quit after refusing to launch what she called a politically driven investigation into Biden-era climate spending, exposing deepening rifts in the US’s premier law enforcement agency.

Denise Cheung, head of criminal prosecutions in Washington, resigned on Tuesday after Trump appointees demanded she open a grand jury investigation into Environmental Protection Agency (EPA) grants based largely on an undercover video, multiple people familiar with the matter told CNN.
