Kimberly Guilfoyle, a former prosecutor and longtime Republican political figure, was sworn in on Monday as the United States ambassador to Greece, a post that had remained vacant for months amid partisan battles in the US Senate.

Guilfoyle becomes the first woman to represent Washington in Athens.

Her nomination had been stalled until earlier this month, when Republicans turned to the “nuclear option,” a procedural maneuver that allowed them to break through a Democratic filibuster and confirm her with a simple majority.

The ceremony at the US State Department was attended by Trump administration officials, political figures, and family members. Among those in attendance were Michael Rigas, the assistant secretary of state for management and resources; Michael Kratsios, director of the White House Office of Science and Technology Policy; Christos Marafatsos, president of the conservative Greek American group “Greeks for Trump”, as well as and Guilfoyle’s son.

In its statement, the United States Embassy in Athens congratulated Guilfoyle on her appointment and said it looked forward to working with her to advance American interests and further strengthen the partnership with NATO ally Greece. She is expected to arrive in Athens at the end of October to present her credential and formally take up her duties.
