President Donald Trump has asked aides and advisers if they believe Elon Musk's behavior over the past 48 hours could be related to his alleged drug use, privately seeking to understand the tech billionaire's broadsides against him while signaling publicly he doesn't care, a source familiar with the conversations told CNN. In his own telling, Trump is not wasting any time thinking about the man who, one week ago, was receiving a giant golden key in the Oval Office and has since lobbed insults toward its occupant. The president told CNN's Dana Bash in a brief phone call Friday morning he was "not even thinking about Elon" and wouldn't be speaking to Musk "for a while."
