President Trump has warned that Robert Mueller would be crossing a "red line" if he poked around in the Trump family's finances—and apparently Mueller is now prepared to find out what awaits him on the other side of that line. A source has revealed to Bloomberg that the special counsel subpoenaed Deutsche Bank a few weeks ago for records on the institution's business dealings with Trump and his family, and the Guardian reports those records have now been turned over to Mueller's team. Deutsche Bank, which has refused to volunteer information to Democratic lawmakers on the $300 million or so Trump was loaned years ago for real estate deals, is staying relatively tight-lipped on the Mueller request, simply telling Bloomberg in a statement: "Deutsche Bank always cooperates with investigating authorities in all countries."
Per Reuters, the source says the Mueller inquiry focused on "certain money and credit transactions." In July 2016, Bloomberg scrutinized Trump's relationship with Deutsche Bank and found it covered a span of 20 years, with the $300 million equaling about half of his outstanding debt. The Guardian notes it's not clear whether Mueller is going after the data to see if it's somehow tied to Russia or if there's another reason he's looking into it. The paper reported earlier this year that Deutsche had undertaken its own investigation to see if Trump's loans had Russian guarantees buried within them (it says it found no evidence of that). Also said to be Deutsche Bank clients: Ivanka Trump, husband Jared Kushner, and Kushner's mother, Seryl Stadtmauer. Although the Guardian predicts a possible "strong reaction" from Trump over the news, he hadn't publicly commented as of this writing. (Read more President Trump stories.)
