The Justice Department has initiated legal actions against Hawaii, Michigan, Vermont, and New York in response to their planned climate lawsuits targeting fossil fuel companies. This move is part of an effort by the Trump administration to block state-led initiatives aimed at holding the oil and gas industry accountable for climate damage. The administration argues that these lawsuits overstep state authority and conflict with its energy policies. The ongoing legal battles highlight the tensions between federal and state governments over climate change strategies.
