NEW YORK, March 16 (Reuters) – The U.S. Securities and Exchange Commission’s enforcement director has resigned in a sudden move coming ​just over six months after she started on ‌the job, the SEC said in a statement on Monday.

Former military judge Margaret Ryan has led the SEC’s enforcement unit since joining the agency in early September. She has resigned from the agency ‌effective ​immediately, the SEC said in a ⁠statement, confirming Reuters’ earlier ⁠reporting.

Ryan, a former marine who had clerked for well-known conservative judges, had been seen as an unusual pick to lead the 1,400-person enforcement given she had little ​experience specific to securities law. She was tapped by Republican Paul Atkins, who became SEC chairman last ⁠April and took several months to ⁠get top leaders into their roles.

“We have ​achieved things over the past six months and I know ​that this critical work will continue,” Ryan said ‌an email to staff reviewed by Reuters.

Ryan’s tenure coincided with what some lawyers described as relatively spotty or slow enforcement activity at the SEC, a government shutdown and continued ⁠attrition from an agency that has seen an exodus of staff under the Trump administration.

In its statement, the SEC said ⁠Ryan oversaw a “critical ‌course correction within the division”. The agency’s ⁠Republican leadership has sought to focus on ​cases ‌involving outright fraud and market manipulation and ​to move ⁠away from some of the compliance-oriented cases seen under prior leadership.

The SEC is expected to announce a permanent successor in the coming weeks, the agency said in its statement.
