The Department of State announced the renaming to "Donald J. Trump Institute of Peace" on social media with a post that said it was done "to reflect the greatest dealmaker in our nation's history" and added "the best is yet to come".
With the building set to be used as the location for the signing of a new peace agreement between Rwanda and the DRC, the Trump administration appears to have changed its approach to USIP.
Earlier this year, the same building was one of the epicentres of drama surrounding efforts by Elon Musk and the Department of Government Efficiency (Doge), which he then led, to slash government spending.
Staff of the non-profit were removed by the Trump administration and the leadership replaced, until a judge intervened. The future of the organisation is not clear, with the matter still before the courts.
