1. The Trump administration announced plans to repeal President Barack Obama’s signature Clean Power Plan, which will make it nearly impossible for the U.S. to fulfill its commitments under the Paris climate accord. The move is unlikely to halt the decline of coal, since many utilities are already shifting to renewable energy, like solar panels, above.

The White House is also dealing with the president’s feud with Senator Bob Corker, which has raised fears for Mr. Trump’s entire legislative agenda and drawn previously private Republican criticism out into the open. (On Sunday, Mr. Corker accused Mr. Trump of treating his office like “a reality show,” among other comments.)
