Kirstjen Nielsen, the former secretary for the Department of Homeland Security who left her post in April, is rejoining the administration in a minor role.

The White House announced Tuesday evening the appointment of Nielsen as a member of the National Infrastructure Advisory Council, a Department of Homeland Security entity. The board has up to 30 members from the private sector who advise the White House on best practices for reducing physical and cyberthreats to the country’s critical infrastructure.
