What rubbish. They dismantled their database of lies because they no longer needed to invest the personnel and resources in documenting an endless torrent of blatant lies and misinformation coming from Trump. Biden is a politician, and while, like all politicians, he occasionally exaggerates, he is not a serial and pathological liar like Trump. So no database is necessary: Factcheck.org will work perfectly well for Biden, as for all other normal, sane political figures.
