WASHINGTON (AP) — The testimony in Donald Trump’s New York hush money trial is all wrapped up after more than four weeks and nearly two dozen witnesses, meaning the case heads into the pivotal final stretch of closing arguments, jury deliberations and possibly a verdict.

It’s impossible to say how long all of that will take, but in a landmark trial that’s already featured its fair share of memorable moments, this week could easily be the most important.

Here’s what to expect in the days ahead:

WHAT HAPPENS DURING CLOSING ARGUMENTS?

Starting Tuesday morning, prosecutors and defense lawyers will have their final opportunity to address the jury in closing arguments expected to last for much of the day, if not all of it.

The arguments don’t count as evidence in the case charging Trump with falsifying business records to cover up hush money payments during the 2016 presidential election to a porn star who alleged she had a sexual encounter with him a decade earlier. They’ll instead function as hourslong recaps of the key points the lawyers want to leave jurors with before the panel disappears behind closed doors for deliberations.
