OH: Co-founder of firm behind Trump-Russia dossier will not testify before Senate next week.

The committee on Wednesday announced a July 19 hearing that listed Fusion GPS co-founder Glenn Simpson, a former Wall Street Journal investigative reporter, as a witness. His inclusion raised the specter of public testimony about the dossier’s seamy and contested claims of sexual misconduct and a years-long Kremlin conspiracy to get Trump elected.

But the request for Simpson to appear was voluntary, and it’s unclear whether the committee will seek to compel his testimony.

Let the subpoenas fly.
