Special counsel Robert Mueller has subpoenaed President Trump’s family business, demanding that the Trump Organization hand over a trove of documents — including some that are related to Russia, a new report said Thursday.

The order was believed to be the first time Mueller’s team has demanded documents directly related to Trump’s businesses, the New York Times reported.

Trump in the past has said that any effort by Mueller’s team to probe his personal business affairs would cross “a red line.”

The subpoena brings the investigation closer to Trump and his family, as his sons Donald Jr. and Eric now run the company.
