They are both already moving the goalposts from "Biden needs to release the documents" to "The documents aren't important and can't disprove anything." This is their way to buttress her story as it falls apart.

They aren't interested in an investigation to the truth. They are only interested in pushing a story to hurt Biden, even when they know it is bullshit. They want to dig through decades of information to find a speech or conversation they can take out of context to beat on him with.
They either want to install Bernie as the nominee or for Trump to win so they can claim a socialist would have won and get to try to take over the parry again in 4 years.
