James Comey was fired on May 9, 2017. Sarah Sanders, then the White House's deputy press secretary was asked about it by the press on May 10th and the 11th. She did give details, that the agents reached her (or the White House) by "email, text messages." Below are quotes from a
Business Insider article written right after the May 11th press conference:
The press was immediately suspicious.
You can see where Sanders had a problem with this when testifying under oath. If the Mueller attorney questioning her followed the same logic progression in trying to vet this as the press member had, she would likely be asked next, how did the agents contact her? If she gave the same answer -- email, text messages -- she might then be asked to produce some. Which she wouldn't have been able to do since they didn't exist. How would she attempt to explain not producing them? She couldn't simply refuse; she'd be committing obstruction. Say she deleted all of them? That might not play too well! Plus, the danger the investigators would ask to examine the devices in order to have IT experts see if they could retrieve the deleted text messages and emails. She decided to do the safe thing: she swallowed hard and admitted to the hearing that she had been lying. She was willing to take a hit in the media if her testimony was referenced when the Mueller Report eventually came out, in order to avoid an even bigger problem if she tried to stonewall the investigators or mislead them as she had members of the press.
Squeegee Beckenheim is correct. Sanders was saying she'd heard from many FBI agents praising the administration's decision to fire Comey
after the fact. That doesn't make sense to me either for the same reasons I outlined previously. Of course, as we now know, it doesn't have to make sense because it never happened.
