USA officials in Malawi were on Tuesday quoted by local media as saying Mussa's presence in government was "not consistent with Malawi Government stand on corruption."
"It is the position of the United States Government that Mr. Mussa was involved in significant corruption while serving as Malawi's minister of Home Affairs, and, therefore, his presence in government was no longer consistent with the current administration, which has publicly stated its determination to root out and eradicate corruption," US embassy public affairs officer Douglas Johnston, said.
US Secretary of State Michael Pompei on July 3 issued a designation against Mussa, barring him and his wife from entering the USA because of his "involvement in significant corruption."
Mussa was arrested by the ACB in 2017 for his alleged involvement in aiding foreign nationals to obtain Malawi passports while he served as minister of Home Affairs during the Joyce Banda presidency.
The ACB is still pursuing the case against Mussa, the first Malawian official to be barred by the USA from entering that powerful nation.
Mussa is DPP’s vice president for the centre and a former parliamentarian, has commented in the past that he was innocent from any crime until proven guilty by a court of law.
