Russian President Vladimir Putin responded to Obama's accusations that he's lied about the Ukraine with: "Who is he to judge? Who is he to judge, seriously? If he wants to judge, why doesn't he get a job in court somewhere."

Putin's answer brought cheers and clapping from the crowd at the St. Petersburg economic conference where he was interviewed.

The CNBC interviewer asked Putin: "You have said 'we are a room full of adults,' so let's have an adult conversation. President Obama has accused you of untruths, as you know, when it comes to supporting some of the separatist groups in the Ukraine..."

Putin responded through an interpreter:

"Who is he to judge? Who is he to judge, seriously?" The crowd began to laugh and clap. "If he wants to judge people, why doesn't he get a job in court somewhere?"

"I don't think he accused me," Putin added for emphasis. "It's his point of view. And I have my point of view when he comes to certain things."

Then, after a pause, "What is it that interested you about what [Obama] said?"

At that point, both the interviewer and the crowd broke out in laughter.
