Biden was able to make so many changes so quickly because of the precedent set by his predecessor, Donald Trump, says University of Wisconsin-Madison political science professor Kenneth Mayer, author of the book “With the Stroke of a Pen: Executive Orders and Presidential Power.”
“Every president looks for ways to use the powers of the office to accomplish their goals, and Trump was unusually aggressive about it, finding things that really broke the norms,” such as declaring a national emergency on the border to redirect money to build a wall Congress refused to fund, he said.
