Venture capitalist Ben Horowitz and his wife plan to donate "a lot" of money to US Vice President Kamala Harris's presidential campaign, despite backing former President Donald Trump three months ago。In a letter to employees from Andreessen Horowitz, Horowitz's company, he stressed the personal attributes of the donation, saying that he and his wife, Felicia, had known Harris for many years and that she had been "a great friend to both of us."。The news was a blow to Trump.。As both candidates head into the final weeks of the campaign and the most money-burning weeks, the Trump campaign has far less cash on hand than Harris。
