Commanders owner Dan Snyder conducted "shadow investigation" that sought to discredit accusers, document shows

Washington Commanders owner Dan Snyder conducted a "shadow investigation" that sought to discredit former employees making accusations of workplace sexual harassment, hired private investigators to intimidate witnesses, and used an overseas lawsuit as a pretext to obtain phone records and emails, according to a document released by a House committee on Wednesday.

The Committee on Oversight and Reform is investigating the Commanders' workplace culture following accusations of pervasive sexual harassment by team executives of women employees. It released the memo ahead of Wednesday's morning hearing at which NFL Commissioner Roger Goodell testified remotely.

Snyder was invited to testify but declined, citing overseas business commitments and concerns about due process. The committee chairwoman, Rep. Carolyn Maloney, D-N.Y., announced during the hearing that she plans to issue a subpoena to compel him to testify.
