Alphabet Inc. chief legal officer David Drummond is stepping down at the end of the month after unloading millions in stock. His departure comes amid an internal investigation into allegations of sexual misconduct.

The Google parent company notified the Securities and Exchange Commission on Friday that Drummond is retiring, effective Jan. 31. His departure follows the exits of Alphabet co-founders Larry Page, who served as CEO, and Sergey Brin, who was president, in early December.
