It was thought that the former president might be arrested on Tuesday, and charged in relation to alleged hush-money payments to an adult film star. That hasn't happened, but many who have been watching the case still expect charges to come. When they do, what will happen next?

But this isn't the only investigation into Trump's potential crimes. There are more, and they involve more sinister allegations. So who exactly is investigating Donald Trump, and for what? Where do those investigations stand? What would a nomination race and potential presidential campaign look like, if one of the contenders is preparing to face a trial? Or perhaps more than one trial?

GUEST: Aaron Rupar, independent political and policy journalist, author of Public Notice
