The founders of the research firm Fusion GPS, Glenn R. Simpson and Peter Fritsch, wrote a Tuesday New York Times op-ed demanding that their congressional testimony be publicly released.

"Three congressional committees have heard over 21 hours of testimony from our firm, Fusion GPS. In those sessions, we toppled the far right’s conspiracy theories and explained how The Washington Free Beacon and the Clinton campaign — the Republican and Democratic funders of our Trump research — separately came to hire us in the first place," the column explained.

"Republicans have refused to release full transcripts of our firm’s testimony, even as they selectively leak details to media outlets on the far right," Fusion GPS noted. "It’s time to share what our company told investigators."

"We told Congress that from Manhattan to Sunny Isles Beach, Fla., and from Toronto to Panama, we found widespread evidence that Mr. Trump and his organization had worked with a wide array of dubious Russians in arrangements that often raised questions about money laundering," the column continued. "Likewise, those deals don’t seem to interest Congress."

The two also hinted there is still much the public does not know.

"The public still has much to learn about a man with the most troubling business past of any United States president," Fusion GPS revealed. "Congress should release transcripts of our firm’s testimony, so that the American people can learn the truth about our work and most important, what happened to our democracy."
