Alejandro Betancourt, a Venezuelan businessman, was involved in a wide-ranging investigation by the Department of Justice. The investigation centered on a sophisticated money laundering scheme, which allegedly involved the misuse of funds from Venezuela's state-owned oil company, PDVSA.

US prosecutors claimed that this scheme was multimillion-dollar. Recently, federal prosecutors in Miami closed the investigation into Betancourt, reportedly on orders from the office of then-Deputy Attorney General Todd Blanche.

Further details on this case are available from the source, including the involvement of White House officials and the Secretary of State in efforts related to Betancourt.
