A personal email account of White House Chief of Staff John Kelly was hacked, according to an email obtained by Buzzfeed via a Freedom of Information Act (FOIA) request. "As we discussed ... my folks are nervous about the emails you send and ask that you no longer include them on any postings," Kelly wrote. "Then there is hacking which one of my own personal accounts has suffered recently. I do almost everything now by phone or face-to-face comms."
The FOIA email confirms previous reports from Politico that Kelly used a compromised smartphone for months. If it's the same incident (the White House never confirmed the original reports), the attack happened during Trump's transition in late 2016 while Kelly was secretary of homeland security.
