A defense lawyer says a U.S. citizen charged in the United Nations bribery case will plead guilty Wednesday to charges.

Attorney Brian Bieber said Monday that Francis Lorenzo will plead guilty to three charges. Lorenzo is a suspended ambassador from the Dominican Republic who was arrested in the fall.

The plea comes in a case that resulted in the arrest of a former president of the U.N. General Assembly and a billionaire Chinese businessman.

Bieber says Lorenzo will plead guilty to conspiracy to commit bribery, conspiracy to commit money laundering and filing a false tax return.

Bieber says his client decided to plead guilty after reviewing the government's evidence. He says it led him to "accept responsibility for his role in the criminal conspiracies committed by him and his co-defendants."
