US President Barack Obama has said that he ordered Russia's Vladimir Putin to cut it out in a conversation about email hacking ahead of the US election. Implying that the Russian President knew about the hacks, Mr Obama said not much happens in Russia without Vladimir Putin. <br/><br/>The President said he had warned Mr Putin of serious consequences at a summit in September. A month later, the US accused Russia of meddling in its democratic process. Mr Obama's comments came during his last news conference of the year. <br/><br/>The President did not criticise his successor, Republican Donald Trump, by name, but said some Republicans were failing to acknowledge the seriousness of Russia's involvement in the US election.<br/>
