Acting SEC Head Remakes Agency Before Trump Pick Confirmed

President Donald Trump’s nominee to lead the agency that regulates Wall Street has yet to be confirmed, but the sweeping changes to the watchdog from his temporary stand-in are starting to pile up.

It was the first of many changes at the regulator under the acting chair, and a sign of things to come.
