Federal prosecutors have rested their case after several weeks of testimony in the corruption trial of state Sen. Dean Skelos and his son Adam.

The defense also rested Tuesday without calling any witnesses or inviting Skelos or his son to the stand.

Federal prosecutors alleged that the former state Senate majority leader conspired and shook down three different companies to pay his son Adam cash or give him no-show jobs in return for legislation that favored those businesses.

In their summation to the eight women and four men on the jury, prosecutors laid out a chain of events, emails and wiretapped phone conversations that they say illustrates a classic quid pro quo.

Prosecutors said it was a "violation of Skelos' oath of office," adding that the situation was a "cash cow" for his son.

Adam and Dean Skelos have both denied the charges. Their attorneys say the senator's office was never for sale. However, prosecutors alleged Adam Skelos profited in the six-figure range by peddling his father's influence in Albany.

Defense attorneys for Dean and Adam Skelos are expected to sum up their cases Wednesday.

The jury could start deliberating Wednesday afternoon or Thursday morning.
