The co-founder of the firm tied to a controversial opposition research dossier on President Donald Trump has agreed to talk to the Senate Judiciary Committee behind closed doors, it was announced Tuesday.
In exchange, the panel will drop its subpoena of Glenn Simpson, co-founder of the Washington-based strategy firm Fusion GPS, The Hill reported.
The subpoena was issued after Simpson declined the committee's request to appear before lawmakers in a public hearing.
"However, since that time, Mr. Simpson, through his attorney, has agreed to provide a transcribed interview and requested that the subpoena compelling his attendance at Wednesday's hearing be waived," committee chair Sen. Chuck Grassley, R-Iowa, and ranking member Sen. Dianne Feinstein, D-Calif., said in a statement, The Hill reported.
"We've reached an agreement on this request and have withdrawn the subpoena."
Fusion GPS came to the committee's attention after a dossier it had commissioned from a former British spy during the campaign was published. The dossier contains salacious allegations about Trump that haven't been verified.
The panel also issued a subpoena compelling Trump's former campaign manager Paul Manafort to appear Wednesday.
Manafort met with congressional investigators on the Senate Intelligence Committee Tuesday to discuss a June 2016 meeting between Trump campaign members and a Russian lawyer, who had promised dirt on then-Democratic candidate Hillary Clinton.
