WASHINGTON — President Trump called on the Justice Department Tuesday to prosecute former President Barack Obama for allegedly ordering an assessment that Russia meddled to help him with the 2016 election.“After what they did to me, whether it’s right or wrong, it’s time to go after people. Obama has been caught directly,” Trump said in the Oval Office.“If you look at those papers, they have them stone cold, and it was President Obama… the leader of the gang was President Obama, Barack Hussein Obama. Have you heard of him?”
