Has to happen in a single day. Similar to https://en.wikipedia.org/wiki/2017_Women's_March which reported between 3,267,134 and 5,246,670 total participants in the US. I'll resolve based on a consensus of credible media sources and/or wikipedia.
Update 2025-02-01 (PST) (AI summary of creator comment): Anti-Trump Protest Definition Clarification
A protest does not need to be solely a demonstration against the person of Donald Trump. It is sufficient if it is motivated by his policy positions, rhetoric, or their perceived impact.
For example, the Women's March qualifies as an anti-Trump protest because it was prompted by Trump’s policy positions and rhetoric.
Update 2025-04-06 (PST) (AI summary of creator comment): Eligible Protest Clarification:
Any type of protest qualifies: The event does not need to be a march; any protest is sufficient as long as it is motivated by Trump’s policy positions, rhetoric, or their perceived impact.
Example Provided: The Women’s March is given solely as an example of a protest that would qualify

CNN is reporting "millions of people".
@dlin007 Thank you!
Wikipedia now cites claims of 3 million for Hands Off, from both organizers directly and organizers via CNN, though it does not yet make the attendance claim itself.
@TimothyJohnson5c16 That is correct. I regret not making this more clear, and have edited my comment now. I appreciate the correction!
@EricMoyer yes. per wikipedia:
> The Women's March[11][12][13][a] was a worldwide protest on January 21, 2017, the day after the first inauguration of Donald Trump as the president of the United States. It was prompted by Trump's policy positions and rhetoric, which were and are seen as misogynistic and representative as a threat to the rights of women.
