President Joe Biden allegedly used several pseudonyms when communicating via email with his son Hunter and Hunter’s Ukrainian business partners, according to a House Oversight Committee investigation.

On Thursday, Rep. James Comer (R-KY), as head of the committee, requested records from the National Archives of any communications between “Robert Peters, Robin Ware, [or] JRB Ware” and Hunter Biden and his former business partners, Eric Schwerin and Devon Archer.

“Joe Biden has stated there was ‘an absolute wall’ between his family’s foreign business schemes and his duties as Vice President, but evidence reveals that access was wide open for his family’s influence peddling. … The National Archives must provide these unredacted records to further our investigation into the Biden family’s corruption,” Comer said, per a press release.

Comer claimed the communications took place during Biden’s vice presidency. Emails from Hunter’s laptop show exchanges between the president’s son and “Robert Peters,” oftentimes on the topic of Ukrainian policy, according to the Washington Examiner. Hunter was reportedly informed of his father’s schedule on several occasions when significant diplomatic activity between the United States and Ukraine occurred.

Hunter, in an email to “Robin Ware” in 2014, appeared to advocate for the hiring of John McGrail at the White House. McGrail was hired as deputy counsel to the vice president the following month and later promoted to counsel, the Washington Examiner reported.

Additionally, Hunter’s laptop reportedly contained other emails from Biden’s purported pseudonyms that were of a more personal nature.

Archer, one of Hunter’s former business partners, told the House Oversight Committee this year that the president’s son would regularly ‘conference in’ his father on business calls with foreign associates. This allegedly included calls with Ukrainian business leaders as the then-vice president oversaw U.S. policy in the country, as previously reported by The Dallas Express. Archer also confirmed Biden would meet with some of Hunter’s business associates in person.

An IRS whistleblower previously provided evidence from the agency’s investigation into Hunter that the then-vice president was involved with his son’s business deals. This included an FBI interview where a business partner claimed there were discussions about having Biden involved in a deal with a Chinese partner so long as he declined to run for president in 2020.
