You are referring to the text of Sanhedrin, 43a which does not mention Jesus, but speaks of someone named "Yeshu"
Here is the write up from the link I provided in my earlier message:
"
Summary
Here we have the story of the execution of Yeshu. Like Ben Stada, he was also executed on the eve of Passover. Before executing him, the court searched for any witnesses who could clear his name, as was normally done before any execution. Ulla, however, questioned this practice. An enticer, due to the biblical mandate not to be merciful, should not be afforded this normal consideration. The Talmud answers that Yeshu was different. Because of his government connections, the court tried to search for any reason not to execute him and upset the government.
Proof
Again we see Yeshu. All of the proofs from above connecting Yeshu to Jesus apply here as well. Additionally, the execution on the eve of Passover is another connection to Jesus as above with Ben Stada.
Problems
1. As mentioned above with Ben Stada, the Synoptic Gospels have Jesus being executed on Passover itself and not the eve of Passover.
2. As above, Yeshu lived a century before Jesus.
3. Yeshu was executed by a Jewish court and not by the Romans. During Yeshu's time, the reign of Alexander Janneus, the Jewish courts had the power to execute but had to be careful because the courts were ruled by the Pharisees while the king was a Sadducee. It seems clear why the courts would not want to unneccesarily upset the monarch by executing a friend of his. During the Roman occupation of Jesus' time, there is no indication that the Jewish courts had the right to execute criminals.
3. There is no indication from the New Testament that Jesus had friends in the government."
