John Kerry, the former Secretary of State, is set to leave his position as the Special Presidential Envoy for Climate Affairs, according to two sources within the US administration on Saturday.
Kerry has held this role for three years, but he intends to assist President Joe Biden in his re-election campaign.
One of the sources familiar with the situation informed Reuters that Kerry informed his staff of his decision on Saturday after speaking with Biden on Wednesday.
The source, who requested anonymity, mentioned that the U.S. administration has not yet decided on Kerry's successor.
Both sources indicated that John Kerry will step down later this winter.
Kerry previously served as the Secretary of State during the administration of former President Barack Obama and played a crucial role in mediating the Paris Agreement on Climate Change in 2015.
This agreement saw nations commit to taking action to combat climate change.
Before his role as Secretary of State, Kerry served as a US Senator from Massachusetts and was the Democratic Party's presidential nominee in 2004, though he lost to former Republican President George W. Bush.
The news of Kerry's departure was initially reported by Axios.
