Source: Durham expanding team, making "excellent progress"

Special Counsel John Durham is expanding his team and making “excellent progress” on his investigation into the origins of the Trump-Russia probe, a federal law enforcement official familiar with the investigation told Fox News.

Fox News has learned that Durham, the U.S. attorney for Connecticut, who Barr appointed in October as special counsel, is adding prosecutors to his team.

It is unclear, at this point, who those prosecutors are.
