(U.S. Department of Justice via AP)HARTFORD, CT – The man leading the inquiry into the origins of the Russia probe is no stranger to politically sensitive investigations. That investigation led to special counsel Robert Mueller's probe of Russian interference in the election. But the parameters of his investigation have never been defined for the public, making it unclear what problems or misconduct from the early days of the Russia probe he is searching for. In Boston, Durham led a task force that investigated the FBI's relationship with mobsters.

Warren says that, far from having boxed herself in politically, she's been working on her health care plan for months and still sees it as a winning issue. "You're going to get health care with no premiums, no deductibles, no fear of bankruptcy if you have a health emergency." Sara Collins, vice president for coverage and access with the nonpartisan Commonwealth Club, said the key involves changing how the health care tab is divided up among employers, government and individuals. Unlike Warren, Sanders has already released payment options, including higher taxes on wealthy Americans and an employee payroll tax of 7.5%. But that would give federal authorities more control over employee health costs than employers, potentially affecting jobs.
