(Reuters) – Lawyers are investigating the actions of Sheryl Sandberg as chief operating officer at Meta Platforms Inc over several years. The Wall Street Journal reported Friday that the Wall Street Journal cited people who were familiar with this matter.

According to the WSJ, several employees were interviewed as part of the investigation into Facebook-parent Meta. The probe began at least last autumn.

Reuters reached out to Meta and Sandberg for comments but they did not respond immediately.

The report said that one of the areas being examined was the support provided by Meta to Sandberg’s foundation Lean In and the promotion of Option B, Facing Adversity and Building Resilience and Finding Joy.

Sandberg, who was in close contact with Mark Zuckerberg and drove the global growth of the largest social network on the planet, announced her resignation from Facebook earlier this month after fourteen years.

Javier Olivan, Chief Growth Officer is to assume the role of chief operating officer. Zuckerberg stated that he does not intend to replace Sandberg directly in the existing company structure.

Sandberg indicated that she will remain on the Meta board even though she has left the company in fall.
