The salacious dossier that paints President Donald Trump in a less than favorable light continues to haunt the commander-in-chief, who has done everything to try and discredit it. He had stepped back from running the panel's probe into Russian meddling in the USA election amid controversy, though he kept his job as committee chairman and remains involved in some issues related to the investigation.
Fusion GPS has refused to say who payed for the dossier, which was compiled by retired British intelligence officer Christopher Steele.
In September 2015, Fusion GPS began their investigation into Trump - on behalf of an anonymous Republican donor, hoping to prevent the political outsider from becoming the Republican nominee for president.
The research, according to reports, was initially financed by anti-Trump Republicans before being continued by Democrats during the 2016 general election.
Members of Fusion GPS, the firm responsible for the dossier, were subpoenaed to appear before the House committee on Wednesday but invoked the fifth amendment, Fox News reports.
"No American should have to experience today's indignity". The HIC had them appear anyway.
Committee Chairman Devin Nunes of California didn't attend the interview.
President Donald Trump and Russia's President Vladimir Putin speak during their meeting on the sidelines of the G20 Summit in Hamburg, Germany, on July 7.
He is apparently suggesting Russian Federation, the Democrats or the Federal Bureau of Investigation paid for the dossier - or that they all cooperated together to fund the file? He made clear that his clients would invoke their Fifth Amendment rights.
In August, Fusion GPS co-founder Glenn Simpson testified to the Senate Judiciary Committee for 10 hours, Levy said.
The 35-page document made unverified allegations about Mr Trump and some of his campaign staff's contact with Russian Federation officials. The claim earned the report the nickname the "pee-tape" or the "golden shower" dossier.
