The Gospel according to John provides an interesting account:
‭John 18:33-38 ESV‬
[33]  So Pilate entered his headquarters again and called Jesus and said to him, “Are you the King of the Jews?” [34] Jesus answered, “Do you say this of your own accord, or did others say it to you about me?” [35] Pilate answered, “Am I a Jew? Your own nation and the chief priests have delivered you over to me. What have you done?” [36] Jesus answered, “My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I might not be delivered over to the Jews. But my kingdom is not from the world.” [37] Then Pilate said to him, “So you are a king?” Jesus answered, “You say that I am a king. For this purpose I was born and for this purpose I have come into the world—to bear witness to the truth. Everyone who is of the truth listens to my voice.” [38] Pilate said to him, “What is truth?” After he had said this, he went back outside to the Jews and told them, “I find no guilt in him. 

Jesus was not concerned with worldly power. He was concerned with ushering in the Kingdom of God. Remember, Satan promised Jesus the world as He was being tempted in the wilderness.  Jesus addresses the Sanhedrin as they are accusing him prior to Pilots to bring forth any accusations of anything that He said were false and they were unable to. The Pharasees are merely trying to appeal to Roman brutality in order to get Rome to kill Jesus.
