President-elect Donald Trump is promising plenty of Day One action to fulfill his campaign promises. At a rally on the eve of his inauguration, Trump told supporters he’d be taking quick action on everything from cracking down on the southern border to promoting oil drilling, and eradicating diversity programs. He also promised to roll back executive actions by Joe Biden “within hours.” The president-elect told the crowd he’ll be signing “lots” of orders that are going to make them “extremely happy.”
