Obama used a pseudonym in emails with Clinton, FBI documents reveal - POLITICO:
"President Barack Obama used a pseudonym in email communications with Hillary Clinton and others, according to FBI records made public Friday.
The disclosure came as the FBI released its second batch of documents from its investigation into Clinton’s private email server during her tenure as secretary of state.
...In an April 5, 2016 interview with the FBI, Abedin was shown an email exchange between Clinton and Obama, but the longtime Clinton aide did not recognize the name of the sender.
"Once informed that the sender's name is believed to be pseudonym used by the president, Abedin exclaimed: 'How is this not classified?'" the report says.
 "Abedin then expressed her amazement at the president's use of a pseudonym and asked if she could have a copy of the email."
...The State Department has refused to make public that and other emails Clinton exchanged with Obama.
Lawyers have cited the "presidential communications privilege," a variation of executive privilege, in order to withhold the messages under the Freedom of Information Act..."
