White House deputy chief of staff Stephen Miller, the architect of President Donald Trump’s mass deportation agenda, is playing an active role in discussions about recruiting new federal workers, according to a new report.

Trump’s government has started ramping up hiring again after the Department of Government Efficiency slashed hundreds of thousands of federal jobs last year, The Washington Post reports.

“We probably have some skills that we now need to hire back, quite frankly,” Scott Kupor, director of the Office of Personnel Management, told the outlet. “There’s no question anytime you do restructurings … sometimes you over-restructure, sometimes you under-restructure.”

Amid this effort, Miller has been playing an active role in hiring discussions, two sources familiar with the issue told the Post. They said Miller has emphasized hiring young applicants and wants new workers to have views aligned with Trump’s goals.
