US judge temporarily bars prosecutors' use of evidence from key figure in Comey case

A U.S. judge has temporarily barred prosecutors' use of evidence from a key figure in the Trump administration's now-dismissed criminal case against former FBI Director James Comey, according to a court document.

The material is from Daniel Richman, a law professor and former attorney to Comey, and would likely be central to any effort by prosecutors to revive the case against Comey.
