Sen. Tom Carper, D-Delaware, sent a letter to White House Counsel Donald McGahn to request information on whether the White House staff’s reported use of private email accounts complies with the Presidential Records Act.

“Recent public reports indicate that at least four senior officials in President Trump’s administration, including counselor to the president, White House press secretary, chief strategist and senior counselor and a senior advisor to the president, maintained active email accounts on a private Republican National Committee email system while serving in the White House,” Carper wrote in a joint letter with Sen. Claire McCaskill, D-Missouri.

Since these reports were initially published, it has been reported that “the RNC has deleted the emails belonging to three of these White House staffers” the senators continued. “As you know, the Presidential Records Act carries specific disclosure requirements for official business conducted using non-official electronic messaging accounts.”

The senators asked the White House Counsel to provide information no later than Feb. 10 to determine that the White House staff’s use of private email accounts is in compliance with the Presidential Records Act.
