Tesla employees and investors are speaking out over fears that CEO Elon Musk’s alliance with Donald Trump undermines its reputation and sustainability mission.

Tesla’s financial tale, however, has taken a turn since Trump took the oath of office with Tesla stock down over 17% since Jan. 21, as of midday Friday. Just weeks before the inauguration, Tesla reported the first full-year drop in global sales in its history as a public company, according to a report from CNN.

The case is a reminder of how much of Musk’s wealth comes from taxpayers. His companies have government contracts worth hundreds of millions of dollars a year.
