As the criminal trial of Donald J. Trump began its seventh week, the prosecution and the defense made their final pitches to jurors, sending the landmark case into deliberations on Wednesday.

A defense lawyer, Todd Blanche, spent three hours Tuesday hammering Michael D. Cohen, the prosecution’s star witness, including accusing him of perjury. He attacked Stormy Daniels, the porn star whose account of a tryst with Mr. Trump in 2006 set in motion the charges the former president faces.

The prosecution countered with an even longer, more detailed summation, pushing into the evening. A prosecutor, Joshua Steinglass, guided jurors through reams of evidence they had introduced and elicited, including testimony, emails, text messages and recordings.

Mr. Trump, 77, is charged with falsifying 34 business records to hide Mr. Cohen’s reimbursement for a $130,000 hush-money payment he made to Ms. Daniels. Mr. Trump has denied the charges and the sexual encounter.

Once deliberations begin Wednesday, no one knows how long they will take. If convicted, Mr. Trump — the presumptive Republican presidential nominee — could face prison or probation.

Here are five takeaways from closing arguments and Mr. Trump’s 21st day on trial.

‘Michael Cohen is a liar’ was a refrain. It may be the defense’s best bet.

“The human embodiment of reasonable doubt.”
