Fusion GPS Co-Founder Will Answer Questions -- But Not Publicly, and Not With Senators Present

From the Washington Examiner:

Glenn Simpson, the co-founder of the firm that assembled the infamous "Russian dossier" that purported to offer intelligence about then-presidential candidate Donald Trump, will be interviewed by the Senate Judiciary Committee later this month. 

Simpson's interview, however, will most likely be with committee staff instead of the senators themselves, according to a report by Politico, which cited a source familiar with the issue. 

The funding for the dossier has become of increasing interest for conservatives, as it assembled a host of allegations against Trump while he was a candidate, most of which have either been debunked or can't be proven. Many of the sources of the claims in the dossier also can't be pinned down with any accuracy. 

The dossier was used in part to obtain a warrant to surveil Trump associate Carter Page in 2016, according to a report by the Washington Post in April. Page has constantly mocked the document as the "dodgy dossier."
