Senate Democrats on Monday said that an F.B.I. background check on Pete Hegseth, President-elect Donald J. Trump’s pick to lead the Pentagon, omitted key details on major allegations against him, in part because it did not include interviews with critical witnesses.
One missed opportunity came when the bureau did not interview one of Mr. Hegseth’s ex-wives before its findings were presented to senators last week, according to people familiar with the bureau’s investigation.
The clamor comes on the eve of Mr. Hegseth’s confirmation hearing, and just days after officials from Mr. Trump’s transition team briefed Senator Roger Wicker of Mississippi, the panel’s top Republican, and Senator Jack Reed of Rhode Island, its top Democrat, on the F.B.I.’s background check.
