WASHINGTON   President Trump said on Thursday that his administration was answering  a call to action  by rolling back regulations on environmental protections, health care, financial services and other industries as he made a push to showcase his accomplishments near the end of his first year in office.The remarks highlighted an area where Mr. Trump has perhaps done more to change the policies of his predecessor than any other, with regulatory shifts that have affected wide sections of the economy. We are just getting started,  Mr. Trump said, speaking from the Roosevelt Room of the White House. He described progress so far as the  most far-reaching regulatory reform  in United States history, a claim he did not back up.  In 1960, there were approximately 20,000 pages in the Code of Federal Regulations. Today there are over 185,000 pages, as seen in the Roosevelt Room. Today, we CUT THE RED TAPE! It is time to SET FREE OUR DREAMS and MAKE AMERICA GREAT AGAIN!A post shared by  President Donald J.

C.E.O.s appear to be responding to the administration s energetic focus on regulation,  Joshua Bolten, the roundtable s president, said this month.   New York Times
