The Trump administration has accused Federal Reserve Governor Lisa Cook of mortgage fraud, a federal crime. But there’s still a lot we don’t know.

President Donald Trump has called on Federal Reserve Governor Lisa Cook to resign amid a claim by a top administration official that she may have engaged in so-called mortgage occupancy fraud by falsely labeling a secondary home as her primary residence to get better loan terms.

Trump on Wednesday called for economist Lisa Cook to resign from the Fed Board of Governors over allegations of mortgage fraud.
