What is sufficient evidence to convict a defendant of money laundering?

Cha argues that there was insufficient evidence to convict him of money laundering because the government failed to prove that he had the intent to " 'conceal or disguise' the nature, location, source or control of the proceeds of an unlawful activity." There is sufficient evidence to support a conviction if, viewing the evidence in the light most favorable to the government, "any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt."
