Trump once again came out to "slap" the gossip that Musk was taking drugs: "I'm not aware of anyone saying that he was taking drugs, and I don't believe those rumors." He also added: "We used to have a good relationship, and I wish him all the best, very good luck."
• Musk rumors denied
In a highly watched interview, Trump publicly denied the rumors that Musk was taking drugs, and said that these rumors were "unfair" - at least now it seems that he was not hurt by those rumors.
• Attitude changed from cold to warm
Although the two had a bad relationship before, Trump threatened to cancel Musk's government contracts, but now he suddenly became "friendly and honest", saying "We have a good relationship and wish him well." Is it a hint that a public reconciliation is imminent? 
Trump suddenly changed his attitude towards Musk today, from previous ridicule and attacks to public expression of goodwill, saying that he did not take drugs and wished him all the best. At first glance, it seems to be letting go of prejudices, but in fact it is more like a political calculation.
Musk has a great voice in social media and the technology industry, and his influence is spread across independent voters, young people, the middle class and business leaders. Trump knows that in order to push the current Great Beauty Act through Congress smoothly, he must win more support from the middle voices and the technology community. Although Musk may not publicly stand in line, as long as he does not oppose or sing a different tune, it is a victory in itself.
Trump's overtures are more like a shrewd political operation. He is not really reconciling with Musk, but hopes to reduce conflicts in exchange for Musk's silence or neutrality. Behind this are both considerations of congressional games and precise grasp of the election situation.
Trump has never softened his tone for no reason. He changed his attitude towards Musk not because of emotions, but because of interests. This sudden easing reflects not reconciliation, but a layout around political considerations.
