As vice president, Joe Biden kept a variety of private e-mail addresses from which he would sometimes forward and receive government correspondence, Hunter Biden’s laptop shows.

“Robin Ware,” “Robert L. Peters” and “JRB ware” were three such pseudonyms on e-mails that mixed official and family business.

In a four-week period in 2016, for instance, John Flynn, who worked in the Office of the Vice President, sent Joe his official daily schedule to his private e-mail address Robert.L.Peters@pci.gov and copied Hunter.

There were 10 such e-mails copied to Hunter between May 18 and June 15, 2016.

In one e-mail from Flynn to Joe, a k a Robert Peters, on May 26, 2016, and copied to Hunter, the schedule includes “8.45am prep for 9am phonecall with Pres Poroshenko.”

Poroshenko was president of Ukraine and, at the time, Hunter was being paid $83,333 a month to sit on the board of corrupt Ukrainian energy company Burisma Holdings Ltd. Hunter introduced top Burisma executive Vadym Pozharskyi to his father in April 2015 at a dinner at Café Milano in Washington, DC.

In December 2015, Biden famously threatened Poroshenko that he would withhold $1 billion in US aid unless he fired Ukraine’s top prosecutor Viktor Shokin, who at the time was investigating Burisma owner Mykola Zlochevsky. Shokin was removed from office on March 29, 2016.

State Department officials have testified that they tried to raise concerns directly with Biden that his son’s Burisma involvement was a conflict of interest that undermined US anti-corruption efforts in Ukraine, but they were rebuffed.

Joe forwarded another e-mail about Ukraine through one of his pseudonymous private e-mail addresses, RobinWare456@gmail.com, to Hunter and his brother Beau, then Delaware attorney general, on March 26, 2012.

The e-mail was from Deputy Secretary of State (now Secretary of State) Antony Blinken, forwarding an e-mail from US Ambassador to Ukraine John Tefft: “Beau visited Kyev [Ukraine] on the Friday and gave a talk on corruption at the Hyatt . . . then attended reception at the residence where he met many young Ukrainian lawyers. We received many compliments on his presentation and for simply a frank discussion of a problem that still bedevils this country.”
