Mai Ahmad Fatty told journalists in neighboring Senegal that already they have determined Jammeh made off with more than USD 11.4 million during a two-week period alone.
"The Gambia is in financial distress. The coffers are virtually empty. That is a state of fact," Fatty said. "It has been confirmed by technicians in the ministry of finance and the Central Bank of the Gambia."
Fatty said officials with the new government "regret the situation" and would stop any additional belongings of Jammeh from leaving Gambia. It appeared, though, that the major damage had been done, leaving Gambia with little recourse to recoup the funds.
Jammeh, who ruled this impoverished West African nation for more than 22 years, went into exile late Saturday under mounting international pressure. He is now in Equatorial Guinea, home to Africa's longest-serving ruler.
A regional military force that had been poised to force out Jammeh if diplomatic efforts failed rolled into Gambia's capital, Banjul, last night to secure it for Barrow's arrival.
Hundreds greeted the force's approach to the president's official residence, State House, cheering and dancing, while some people grabbed soldiers to take selfies.
