“Senate Democrats on the Judiciary Committee have referred a letter concerning Supreme Court nominee Brett Kavanaugh to the FBI,” BuzzFeed News reports.

“The contents of the letter have been closely guarded by Sen. Dianne Feinstein, the ranking member on the Senate Judiciary Committee, as well as California Rep. Anna Eshoo, who originally received the letter and shared it with Feinstein, according to sources familiar with the matter. But whispers of what it contains have made the rounds across Capitol Hill over the past week.”

The Intercept: “The specific content of the document, which is a letter from a California constituent, is unclear, but Feinstein’s refusal to share the letter has created tension on the committee, particularly after Feinstein largely took a back seat to her more junior colleagues last week.”
