In addition to the stuff you already know, he was also “subpoenaed last week by the special counsel, Robert S. Mueller III, to testify before a grand jury as part of the investigation into possible links between Mr. Trump’s associates and Russia.” He’s testifying in front of the House Intelligence Committee today.
