“Mr. Kushner’s active role in arranging meetings and engaging in diplomacy, both in public and private, coupled with his use of unofficial email, raises questions as to whether any communications regarding representatives of foreign governments occurred through unofficial channels and could have been compromised,” Cardin wrote.

Sources told ABC News that Kushner and Ivanka Trump have used three different emails for business.

Cardin is asking both men if they are aware of any “unofficial” communications between a State Department employee and a White House employee — including if Tillerson himself has received an email or text message — or if either of them know if a White House official has communicated with a foreign government or official through non-official means. 

President Trump and Republicans repeatedly attacked Hillary Clinton, the 2016 Democratic presidential nominee, for her use of a private email account while secretary of State.
