Senior staffers for Senate Republicans knew about Deborah Ramirez’s sexual misconduct allegation against Supreme Court nominee Brett Kavanaugh as early as last week, resulting in their bosses pushing to hold Kavanaugh’s confirmation vote sooner, according to a Sunday New Yorker report.

Senate Democrats also found out last week, and at least two of the four who knew reportedly started investigating the allegation to assess its credibility. “This is another serious, credible, and disturbing allegation against Brett Kavanaugh,” said Sen. Mazie Hirono (D-H). “It should be fully investigated.”

Sen. Dianne Feinstein (D-CA) is now calling for the confirmation hearing to be delayed until the FBI can investigate Ramirez’s alleged assault, which she says occurred when she and Kavanaugh were attending Yale, as well as that of professor Christine Blasey Ford, who says she was assaulted by Kavanaugh when they were both in high school.
