President-elect Donald Trump is set to declare a national energy emergency as soon as he is sworn into office Monday in an effort to meet his campaign promise of lowering energy costs for Americans and reversing the climate policies of President Joe Biden.

“Lowering prices for all Americans is a key priority of the Trump administration,” an incoming White House official told reporters Monday. “The President is taking these actions as soon as possible here on Day One so that we can lower prices as soon as possible for the American people.”
