The Justice Department is suing four states over climate action. The office argued in filings Wednesday that a lawsuit out of Hawaii and pending litigation from Michigan against fossil fuel companies for harms caused by climate change would infringe on the federal government’s authority.

President Donald Trump's administration has sued Hawaii and Michigan to try to stop them from filing lawsuits against major oil companies over the fossil fuel industry's role in climate change, accusing the Democratic-led states of overreach and imperiling domestic energy production.

In an unusual move, the Trump administration pre-emptively sued Hawaii and Michigan to try to stop them from suing oil companies over global warming.
