Washington (CNN)Attorney General William Barr is working closely with the CIA to review the origins of the Russia investigation and surveillance issues surrounding Donald Trump's presidential campaign, according to a source familiar with the matter, broadening an effort that the President has long demanded to involve all major national security agencies.
Barr is working in close collaboration with CIA Director Gina Haspel, Director of National Intelligence Dan Coats and FBI Director Christopher Wray, the source said.
There had been speculation as to why Haspel had been spotted at the Justice Department in recent weeks. Wray testified last week he was assisting Barr.
Trump often called for the Justice Department and others to review how the FBI began investigating the connection between his campaign and Russian meddling in the 2016 election. He told reporters Tuesday he did not direct Barr to call on intelligence agencies to join his review of the Russia probe.
