What are the facts surrounding Rachel Maddow's claims about Elon Musk's supposed $400 million armored Tesla vehicle deal with the U.S. government?

Sean Hannity clarifies that Rachel Maddow's claims about a corrupt $400 million deal for armored Tesla vehicles contain critical omissions. He explains that the Tesla procurement plan actually originated under President Biden's administration, not Trump's, contrary to Maddow's implication. More importantly, President Trump ultimately canceled this plan entirely, directly contradicting the narrative that Trump was facilitating corrupt deals for his top campaign donor Elon Musk. Hannity uses this example to criticize mainstream media for presenting incomplete information and promoting conspiracy theories without providing essential context.
