Cohen, who pleaded guilty to multiple crimes related to the coordination of hush-money payments to two women, said Weisselberg could answer questions about the $130,000 payment to adult film star Stormy Daniels. The New York Times reported that Weisselberg knew the details of the payments and the reimbursements to Cohen since 2017.

In a secretly recorded conversation before the 2016 election, Cohen can also be heard telling Trump he consulted with Weisselberg on how to coordinate payments to the National Enquirer's parent company, American Media Inc., to buy rights to a story about former Playboy model Karen McDougal's alleged affair with Trump.

In August 2018, Weisselberg was granted immunity by federal prosecutors in exchange for grand jury testimony. It's unclear whether he will agree to appear before the House Intelligence Committee like Cohen.

But many see Weisselberg to be the best positioned, as the Trump Organization's bookkeeper, to help investigators unravel whether Trump or his family members committed financial crimes that have not yet come to light.

"Weisselberg was there at the genesis," Patrick Cotter, a longtime former federal prosecutor, said. "He knows this organization from the beginning. That's a star cooperating witness to have. He has the inside perspective, more than Cohen, more than anyone else. If you're Trump, that's the guy you don't want to cooperate."
