....and it is HARD to get your statement corrected, redacted, changed when DOJ is screaming on one phone, a dead horse head is found on your desk, your lunch has "extra ingredients", and your door is being knocked on by junior FBI types with a battering ram.....while NYPD is on hold on line 2.
Plausible. Also fits in with the late Friday afternoon news dump. Comey has a record of this type of timing, interviewing Hillary on Saturday AM over the 4th of July weekend, then announcing on Tuesday July 5th in the AM there was nothing to pursue in the Hillary e-mail scandal.
