Not really, trump was cooperating too, he even said they would work with them to straighten it out. Negotiations broke down then the fbi raided his home. Didn't Trump say that he would have continued to work with them?
They are still legitimate because Biden did have documents he wasn't supposed to have..and I think he may have lied about knowing he had them, here's why. He has repeatedly stated they were in a secure place...if he didn't know he had them,.then why would they be in a secure place? Unless it's just a coincidence that they ended up in a secure place, and he truly didn't know he had them...and I'm not sure which is worse, that he knew he had them and lied about it, or that he had no idea that he was in possession of top secret/SCI documents..
Again, how did they end up in his possession? Does a vp pack his own belongings when leaving the white house, or do they have a moving company come in to pack his things? If it's a moving company, does that mean those top secret/SCI documents were just laying around, and accessible to those who were packing his stuff up and they got mixed up in other documents and put into boxes? And nobody knew that those boxes contained top secret documents...and who knows where those boxes could have ended up?
If he packed his own things, then again, the top secret docs were just mixed together with regular non classified docs, and they all ended up in the same box?
I would think that they would be a bit more careful when handling such information, to the point that it would be hard to believe they just accidently wound up being packed into boxes as he was leaving. Either these documents were just laying around, to be seen by anyone, including whoever packed his belongings, or he knew he had them.
