Pretty sure that's not an opinion but a fact. Johnson has tried everything to just hide it, even delaying swearing in an elected representative. The shutdown is a real boon for him as he can blame not doing anything about the Epstein files on the shutdown.
The real question though is: are they just delaying this for delaying's sake (I guess hoping people forget or Trump dies or just delaying it until after midterms) or are they actually doing something in the background while the delay is happening? Are they destroying evidence or doing something equally as nefarious?
Though I have to say that the evidence must be extremely damning if they are going to such extremes to cover it.
