The government is making a final push in its case against Brooke Astor’s son.

Closing arguments resumed Monday at the Manhattan trial of Anthony Marshall and his co-defendant, attorney Francis Morrissey.

Prosecutors say Astor – who died in 2007 at age 105 – wasn’t competent to sign documents that increased Marshall’s share of her $198 million estate.

The defense says that although she was suffering from Alzheimer’s, the philanthropist had lucid moments.

Defense lawyers said Monday they objected to prosecutor Joel Seidemann calling the defendants “morally depraved” earlier.

Justice A. Kirke Bartley Jr. said he would instruct the jury to disregard the comment, but he denied a defense request for a mistrial because of it.
