We can hope this actually turns into something, but we've all been burned on that. Here's CNN's reporting:
Officials from the district attorney's office, led by Cyrus Vance, interviewed Cohen at the federal prison in Otisville, New York, where he is serving a three-year sentence after pleading guilty to multiple crimes including campaign finance violations tied to payments to two women alleging affairs with Trump a decade ago. Trump has denied having affairs with the women.
The district attorney opened the investigation last month and sent subpoenas to the Trump Organization and American Media Inc. seeking documents and records relating to payments made to Stormy Daniels and Karen McDougal to silence their allegations ahead of the 2016 presidential election.
The investigation is looking into whether the Trump Organization violated a New York state law involving false business records. Investigators are exploring whether the real estate company falsified its records in describing the reimbursement to Cohen for the payments.
