 Tesla Inc. TSLA Chief Executive Elon Musk on Tuesday shed more light onto the often-acrimonious dealings between the EV maker and JPMorgan Chase Co. JPM Musk said in a federal trial over his funding secured tweets on Tuesday that the relationship between Tesla and bankers at JP Morgan is very negative, and that Musk decided to take away all of Teslas commercial-banking business from JP Morgan. Musk also said that he has asked Chief Executive Jamie Dimon for support for Tesla, but that Dimon had declined to provide that support.
