PALO ALTO, California -- U.S. electric-vehicle maker Tesla on Tuesday reported an operating profit of $399 million for the January-March quarter, down 66% on the year and the lowest in roughly half a decade, as CEO Elon Musk's involvement in the Trump administration turned potential buyers off.
On an earnings call, Musk said he will be allocating "far more of my time to Tesla," starting in May.
