I suppose every administration would like to blame the previous administration for some of their problems. Trump did, so your comment is valid imo.
However, I think the Biden administration has tried to blame every one of its failures on Trump, which is simply preposterous. Probably not every single one... because that would seem almost impossible no matter how smoothly oiled a propaganda machine may be. But they sure do blame Trump for any of their problems / failures that get any publicity from the media.
