Jamie Dimon, the billionaire head of the U.S.’ biggest bank, lauded Tesla CEO Elon Musk, the richest man on the planet and a key part of President Donald Trump’s administration, this week, putting an end to years of head-butting between the billionaires’ companies as Dimon becomes the latest billionaire warming to Musk or Trump.

JPMorgan CEO Jamie Dimon said he and Elon Musk “hugged it out” and put aside nearly a decade of tense interactions thanks to a conversation the pair had at a conference last year.
