MIAMI – The U.S. Attorney’s Office for the Southern District of Florida proudly celebrated the retirements of Assistant U.S. Attorney Mary V. “Jena” King and Legal Assistant Niurka “Nikki” Machin during a clap-out ceremony honoring their decades of dedicated federal service.

She has served this community faithfully in defense of the rule of law with the grace, judgment, and compassion throughout her time in the Southern District of Florida.

“Jena’s family’s legacy of public service is woven into the very fabric of our community.

The clap-out ceremony brought together colleagues and leadership to recognize King and Machin as they concluded their federal careers and embarked on the next chapter of their lives. Their legacy of excellence, professionalism, and service will remain an enduring part of the Office’s history.
