This recently broke in The New York Times and is being covered right now by Rachel Maddow:
The Manhattan district attorney’s office is considering pursuing criminal charges against the Trump Organization and two senior company officials in connection with Michael D. Cohen’s hush money payment to an adult film actress, according to two officials with knowledge of the matter.
A state investigation would center on how the company accounted for its reimbursement to Mr. Cohen for the $130,000 he paid to the actress, Stephanie Clifford, who has said she had an affair with President Trump, the officials said.
Both officials stressed that the office’s review of the matter is in its earliest stages and prosecutors have not yet made a decision on whether to proceed.

Apparently the same article also breaks news that there will likely be new tax fraud charges against Michael Cohen unrelated to the 8 crimes he just pleaded guilty to:
As the district attorney, Cyrus R. Vance Jr., considers opening an investigation, the New York State attorney general’s office has moved to open a criminal investigation into whether Mr. Cohen has violated state tax law, an inquiry that would be unrelated to the federal tax evasion charges that he pleaded guilty to on Tuesday, according to a person with knowledge of the state matter.
Part of the import of this news is that these are State crimes, so they can’t be pardoned by Trump. Yes, the same stable genius who just confessed that the money came from HIM.
