US President Donald Trump wrote on his social media platform Truth Social that his country "will not allow" Tehran "any uranium enrichment" as part of an agreement. He added that the "AUTOPEN" (an automatic signature device used as Trump's derogatory nickname for Biden) "should have stopped Iran from 'enriching' long ago." Recent reports indicate that Iran is unwilling to give up its uranium enrichment capabilities as part of an agreement, and this issue has become the core dispute between the parties in negotiations.
