Andrew Ceresney, the former enforcement director of the U.S. Securities and Exchange Commission who is rejoining Debevoise & Plimpton in March, said he believes aggressive enforcement at the SEC will continue under Donald Trump’s administration.

“My view is that the SEC has now re-established itself as an aggressive, tough, but fair regulator and I think that reputation will continue,” Ceresney said in an interview Tuesday, shortly after Debevoise announced that he would return to the firm as co-chair of its litigation department.
