Donald Trump will be sworn in as president Monday, returning to power to enact his sweeping vision of America after leaving his office in shame four years ago.

Tech leaders should have a visible presence at Trump’s inauguration, with Jeff Bezos, Elon Musk, Mark Zuckerberg, Tim Cook, Shou Zi Chew, Sundar Pichai, and Sam Altman all reported to be present. Musk is also scheduled to speak at a pre-inauguration rally, and Zuckerberg will reportedly host a black-tie event on Inauguration Day.
