The letters signed Monday by Gowdy and Cummings cite a Sunday report by Politico, which first reported Kushner's use of the private account. They ask the addressees to share the names of any "non-career official" who has used a personal account to conduct official business or used an "alias" account – that is, an official account that does not use the person's actual name – to do so. They also request the names of any officials who use " text messages, phone-based message applications, or encryption software" to do their jobs.
