That was an unsourced claim. Trump never said that he refused to accept Sessions resignation.
Jeff Sessions is the source.
You can't get any sourcier of a source then the man himself. Sessions just said out his mouth that he offered his resignation. Trump never confirming that he did, if what you say is even true, has no bearing.
What Sessions (the source) said is easily confirmed. Go ask Trump.
It would be more intellectually honest and you people would have more credibility for your emotional, illogical rants if you stopped trying to refute obvious truths with your bullschitt.
Helpful hint.
