In a singular moment for American history, the hush money trial of former President Donald Trump begins Monday with jury selection.

It’s the first criminal trial of a former commander in chief and the first of Trump’s four indictments to go to trial. Because Trump is the presumptive nominee for this year’s Republican ticket, the trial will also produce the head-spinning split-screen of a presidential candidate spending his days in court and, he has said, “campaigning during the night.”
