The US justice department says the former Gambian President, Yayha Jammehj, used the proceeds of bribery and embezzled public funds to buy a mansion in a Washington suburb when he was in power.
Jammeh bought the $3.5m house a decade ago, according to documents presented as part of an effort to seize the property.
He is said to have bought the lavish property through a trust set up by his wife, Zineb Jammeh.
The former president was in power in Gambia for more than 20 years. Jammeh fled the country after losing the 2017 elections and now resides in Equitorial Guinea.
