Assistant US Attorney Jonathan Streeter has told US District Judge Richard Holwell that the government plans to present two more witnesses before wrapping up.
Rajaratnam's lawyer John Dowd said the defence could begin their case later on Tuesday. Since the trail began in March, government lawyers have played secretly recorded phone conversations between Rajaratnam and other alleged conspirators, who provided him with confidential information.
Out of 26 people arrested in the case, 19 have pleaded guilty. 53-year-old Rajaratnam, who is charged with 14 counts of conspiracy and securities fraud, denies wrongdoing.
If found guilty, he faces up to 20 years in prison.
Rajaratnam's old classmates from The Wharton School of the University of Pennsylvania Anil Kumar, a former McKinsey director and Rajiv Goel, a former Intel executive pleaded guilty and testified against him.
The prosecution also called the head of Goldman Sachs, Lloyd Blankfein, as a witness in connection with Rajiv Gupta, a former director at the investment bank, who is also accused of passing insider tips to Rajaratnam.
This week, the defence and prosecution argued about the admissibility of video-surveillance footage that shows another alleged conspirator, Roomy Khan, faxing confidential information on Intel Corp. from late 1997 to early 1998,
