At least six advisers who've worked for the Trump administration have occasionally used private email addresses while discussing government matters.
The news started Sunday with word that President Donald Trump's son-in-law and senior adviser Jared Kushner used a private email account after Trump took office; that was according to Politico and Kushner's lawyer Abbe Lowell.
Kushner's lawyer said he sent "fewer than 100 emails" from that private account. The attorney also mentioned most of those emails were "forwarded news articles or political commentary."
Politico was shown or told about email exchanges between Kushner and former chief of staff Reince Priebus, former chief strategist Steve Bannon and National Economic Council Director Gary Cohn, among others.
Then on Monday, the New York Times reported Priebus, Bannon, Cohn and adviser Stephen Miller also occasionally used private email addresses to discuss government business.
And Newsweek reported Ivanka Trump used a personal domain to contact a government official on at least one occasion in February — but at the time, she was an unofficial member of the West Wing.
She started working at the White House in an official role in March. But multiple ethics experts told Newsweek that as the president's daughter, she could have had a White House email account in February.
President Trump hammered Hillary Clinton during the campaign for using a private email account when she was secretary of state. But Clinton used her private server for all communications, not just an occasional email.
