In one of his first acts as president, Donald Trump effectively halted nearly $200 billion worth of regulations, according to a new analysis.

President Trump has taken aggressive action to curb regulations in his first week, promising to cut 75 percent or "maybe more," and signing an executive order Monday to cut two regulations from the books when every new rule is introduced.

The first move came in the form of a memo to all federal agencies from Chief of Staff Reince Priebus, freezing all recently finalized and pending regulations. The American Action Forum, a center-right policy institute, found the action resulted in stopping rules that would cost the economy $181 billion.

"On day one in office, President Trump’s Chief of Staff, Reince Priebus, signed a memo to all executive agencies imposing a regulatory moratorium," wrote Sam Batkins, director of regulatory policy for the American Action Forum. "This may sound like an extraordinary action, but President Obama’s then-Chief of Staff, Rahm Emanuel, penned an almost identical memo eight years ago."

"According to American Action Forum (AAF) research, this memo put a hold on $181 billion in total regulatory costs, including $17 billion in annual costs, and 5.5 million hours of paperwork," Batkins wrote. "This moratorium freezes 22 rulemakings with annual costs above $100 million and 16 measures with more than $1 billion in long-term costs."
