A Clinton-backed group was reportedly behind the promotion of the unverified Russian dossier that contained scurrilous allegations against President Trump, according to the New York Post.
The Senate Judiciary Committee is considering subpoenaing the research firm Fusion GPS as the firm remains silent about the possibility of funding of the dossier.
The firm has a long history of investigating Republicans at the behest of Democrats. Fusion GPS was hired by Democrats to find damaging information on Trump as well as Mitt Romney in 2012.
Planned Parenthood has also used the firm to attack pro-life activists.
