This week, the FBI search at Donald Trump's Florida resort, Mar-a-Lago, wasn't the former President's first rodeo with the feds. Federal investigators reportedly served an earlier grand jury subpoena and took away sensitive national security documents from his property during a June meeting, CNN reports. The subpoena issued before the June meeting, during which investigators were shown where documents were held in a basement room at the Trump residence and private club, shows how the investigation has escalated and suggests the discussions had become confrontational long before Monday's search. The criminal investigation started with concerns about missing documents raised by the National Archives, which made a criminal referral to the Justice Department.
