In federal criminal cases, cooperating with the government is commonly known as a proffer agreement, interview, proffer letter, or a “Queen for a Day” letter.
A proffer agreement is a written contract between a federal prosecutor and defendant, or a person under a criminal investigation, where they will make an agreement to give the prosecutor useful information. Their statements won't be used against them later in a criminal proceeding.
The word profficial is a combination of the words professional and official. When the two words are combined and used as one, it is usually in reference to someone of great importance who is good at what they do.
