Mueller cleared by U.S. ethics experts to head Russia probe

Former FBI Director Robert Mueller has been cleared by U.S. Department of Justice ethics experts to oversee an investigation into possible collusion between then-candidate Donald Trump's 2016 election campaign and Russia, a spokeswoman said on Tuesday. The department appointed Mueller special counsel last week to ensure an independent probe, but an ethics rule limiting government attorneys from investigating people their former law firm represented raised questions over how Mueller would be allowed to operate.
