In an opinion piece, Amy Sinden, a professor at Temple’s Beasley School of Law, said the president can't rely on GOP cooperation, so he must make use of executive orders to make progress on environment, health and safety. “So what might the president accomplish on his own? Plenty. If, that is, he's willing to use every bit of executive power he can marshal, by directing the regulatory agencies of his administration to move with dispatch to regulate and enforce in a number of vital areas,” Sinden said.
