Hicks was before the committee voluntarily, and she pleaded the inexplicable Trump privilege over all things in response to most questions, so her answers concerning her email were limited.

It is standard practice for lawmakers to ask witnesses about phone numbers and email accounts. But it is uncommon, according to people familiar with the committee process, for a witness to tell lawmakers that he or she no longer has access to past accounts.

From the campaign on, Hicks has supposedly acted as Donald Trump’s email nexus. So her emails during the campaign are of particular interest when it comes to knowing what Trump was told and when. That she’s claiming to be unable to access her campaign email account doesn’t sound like a hoax, it sounds very, very much like an attempt to cover up information. Either Hicks’s email account was provided by a private system connected to the campaign, in which case access should be easily restored, or the email was provided by a public system, all of which have processes for reporting being locked out of an account and restoring access.

It's very difficult to find any legitimate reason why Hicks should be able to claim to no longer have access to her email accounts, unless that reason is that she doesn’t want to admit she has access to her email accounts.

Hicks’ personal email would also seem like a source of potential information concerning her actions in support of Trump, both during the campaign and at the White House. How long would anyone let their personal email be unavailable without taking action to change the situation, unless having that email supposedly locked away was to their advantage?

Corey Lewandowski is scheduled to appear before the same committee on Thursday. It will be interesting to see if Lewandowski, who never served in the White House, also tries to apply Trump’s get out of everything free version of privilege. And someone should inquire about the health of his email.
