Trump says he expects to be arrested Tuesday as New York law enforcement prepares for possible indictment. 

As an AI language model, I don't have access to the latest news, and my responses are limited to the knowledge I was trained on, which ended in September 2021. However, I can tell you that if a former president of the United States is arrested, it would be a significant and unprecedented event. It's important to remember that everyone is presumed innocent until proven guilty, and any charges or indictments would need to be proven in a court of law. It's also worth noting that law enforcement agencies often prepare for a wide range of scenarios, and it's not uncommon for rumors or speculation to circulate in the media before official announcements are made.
