Monday's ruling concerns a subpoena that Vance had issued to Trump's accountants Mazars USA in August 2019 ordering it to furnish documents stretching back to 2011.

"The work continues," Vance said in a three-word statement issued after the ruling.

Vance's probe was initially focused on payments made before the 2016 presidential election to two women who claim they had affairs with Trump, including porn star Stormy Daniels.

But the state-level investigation is also now examining possible allegations of tax evasion, and insurance and bank fraud.
