The Senate Judiciary Committee earlier this month threatened to subpoena the firm, Fusion GPS, after it refused to answer questions and provide records to the panel identifying who financed the error-ridden dossier, which was circulated during the election and has sparked much of the Russia scandal now engulfing the White House.
Fusion GPS was on the payroll of an unidentified Democratic ally of Clinton when it hired a long-retired British spy to dig up dirt on Trump. In 2012, Democrats hired Fusion GPS to uncover dirt on GOP presidential nominee Mitt Romney. And in 2015, Democrat ally Planned Parenthood retained Fusion GPS to investigate pro-life activists protesting the abortion group.
