"This is intended to be a peaceful event. We will be working closely with the City of Palo Alto to ensure that everyone has a safe and inspiring day," it continues.

Many tech workers have opposed Trump, with industry executives voicing concern over the president's immigration policies, particularly his travel ban executive orders, which bar citizens of certain Muslim-majority countries from entering the U.S.

Dozens of tech companies filed a legal brief last month saying that Trump's original travel ban is harmful to U.S. companies.
