United States Ambassador Meg Whitman has resigned.
According to Whitman, it has been an honour to serve the people of America through strengthening relations with Kenya.
"Today, I announced to my team at the U.S. embassy that I submitted my resignation to President Biden," she said.
"I will depart Kenya full of gratitude for the team that has worked tirelessly on my behalf, for the opportunity to serve my country, and for the friendship offered by the government and the people of the beautiful Republic of Kenya."
A source privy to the development said Whitman had opted to leave early.
Her resignation comes a few days after Republican candidate Donald Trump won the presidency.
She was appointed to the role by outgoing President Joe Biden and has served as head of the Kenyan embassy since August 2022.
Whitman said she is proud of leading a people-centred agenda that saved lives, increased security, and created economic opportunities for Kenyans and Americans.
"From delivering emergency funding to alleviate catastrophic flooding in 2023 to the ongoing fight against malaria, HIV, and MPOX, the U.S government prioritises the health and welfare of our friends in Kenya.
"This year, the United States elevated Kenya as its first Major Non-NATO ally in sub-Saharan Africa, reflecting the importance our countries place on standing shoulder to shoulder to protect our shared democratic values and enhance security."
She said her efforts have opened the door for more American companies to do business in Kenya and this has created more trade, jobs and US investments in Kenya.
Whitman noted that, like all ambassadors, she serves at the request of the president and a new president will be taking over the running of the United States.
"The American people have spoken, and a new President will be inaugurated in January. I wish him and his new team success."
She also announced that Chargé d'Affaires Marc Dillard will continue to offer leadership to staff at the embassy as they advance the shared goals on which the Kenya and US bilateral relationship has long been grounded.
"I have no doubt that our 60 years of partnership will continue to strengthen and serve Americans and Kenyans as we aim to build more prosperous, healthy, secure, and democratic nations. Our relations are stronger than ever, and I am confident this trajectory will continue."
