Mueller has subpoenaed a witness for all communications between that person and a number of people, including Trump, with the requested documents including emails, work documents, text messages, telephone logs and other records spanning back to November of 2015, NBC News reported.

The report comes as Mueller continues to probe alleged ties between the Trump campaign and Russian election meddling.

The pace of the probe has appeared to speed up in recent weeks.

Mueller last month unsealed indictments against 13 Russian nationals for their alleged roles in a plot to disrupt and influence the 2016 election, in addition to filing a superseding indictment against Manafort, Trump's former campaign chairman.

He was also able to obtain a guilty plea from Manafort's associate and former Trump campaign aide Rick Gates.

Trump has long denied allegations of collision between his campaign and Russia, calling the investigation a "witch hunt."
