'Other shoes to drop': Ex-federal prosecutor says Mueller's 'very rare' move this week shows something big is coming

Former federal prosecutor Elie Honig this week said that the declaration by special counsel Robert Mueller's office that it is too busy to comply with a request to unseal redacted documents suggests something big is in the works.

While appearing on CNN, Honig explained just how surprising it was to see Mueller's team argue that it faced "the press of other work" and required "additional time to consult with the government" before unsealing the documents.

"When I was raised as a prosecutor, we were raised with the mantra, 'The government is always ready,'" he said. "So even if a judge said to you, 'You're starting trial Monday,' and you knew in your head there's no way I can do it, you'd always say, 'The government is always ready.' So it is very rare to say we can't get it done in time."

Honig then speculated on the potential significance of what Mueller could be working on that is taking up so much time.

"It could be a report, it could be more charges," he said. "I still think there's other people, other shoes yet to drop, so they could be getting ready for that."
