New York County District Attorney Cyrus Vance's office has subpoenaed eight years of President Donald Trump's tax returns.
The grand jury subpoena was delivered to Mazars USA, the longtime accounting firm to Trump and the Trump Organization.
According to CNN, a source says it's part of the DA's investigation into hush money payments.
It isn't clear what the deadline is for Mazars USA to comply.
Any material obtained by a grand jury subpoena is covered by grand jury secrecy rules.
