When will Donald Trump go on trial?

As of my last knowledge update in September 2021, there were no confirmed plans for Donald Trump to go on trial. However, discussions and legal proceedings regarding his potential involvement in various investigations were ongoing. These included investigations into his business practices, financial records, and actions during his presidency. The timing of any potential trial would depend on legal developments, evidence gathering, and decisions made by law enforcement and judicial authorities. For the most current and accurate information, I recommend checking the latest news sources or legal updates. Please note that circumstances may have changed since then.
