President Donald Trump's administration is moving to block a lawsuit Minnesota's attorney general filed almost six years ago alleging that oil companies and a petroleum trade group deceived state residents about climate change. Ellison sued ExxonMobil, Koch Industries, the American Petroleum Institute and refinery company Flint Hills Resources in 2020, accusing them of fraud and deceptive trade practices. The U.S. Justice Department, the law enforcement arm of Trump's administration, filed its own action in federal court in Minneapolis on Monday arguing that the federal government has the authority to regulate greenhouse gases, not states, and Minnesota officials can't unilaterally impose their policy preferences on the rest of the country.

A partisan redistricting battle among states has accelerated ahead of the midterm elections. This comes after a U.S. Supreme Court ruling that weakened the federal Voting Rights Act and opened the way for states to eliminate voting districts drawn for racial minorities. Voting districts typically are redrawn based on census data after the start of each decade. But an unusual spate of mid-decade redistricting broke out after President Donald Trump urged Texas Republicans to reshape U.S. House districts to give the party an edge in the November midterm elections. Democrats in California countered with their own political gerrymandering. More states have followed.
