(WASHINGTON) – Testimony to the U.S. Congress by the head of a political research firm indicates that the Trump Organization’s sales of properties to Russian nationals may have involved money-laundering, the top Democrat on the House Intelligence Committee said on Thursday. The panel released the transcript of a Nov. 14 closed-door interview with Fusion GPS founder Glenn Simpson, whose firm hired a former British spy to research then-presidential candidate Donald Trump’s campaign ties to Russians and produced a dossier. “Those transcripts reveal serious allegations that the Trump Organization may have engaged in money laundering with Russian nationals,” Representative Adam Schiff said. The Trump Organization dismissed the allegations as unsubstantiated. Another Democrat on the Republican-controlled committee, Representative Jim Hines, sought to temper Schiff’s comment, telling CNN that Simpson “did not provide evidence and I think that’s an important point.
