Demonstrations were held throughout the United States on Presidents Day, February 18, 2019, in protest of President Donald Trump's declaration of a national emergency to construct a new wall extending the barrier along the southern border. Because schools were closed on Presidents Day, many young people were able to participate.

Thousands participated across the United States. Some rallies were organized by MoveOn. The reported number of events has varied. According to Pacific Standard, more than 140 events were planned, per a website operated by MoveOn. Bloomberg reported that MoveOn claimed 175 events were planned in 41 states, and HuffPost said the organization claimed more than 260 events were organized in 48 states.

In Connecticut, events were organized in New Haven, Norwalk, and Pomfret. Protesters gathered outside Congresswoman Rosa DeLauro's office in downtown New Haven. More than 60 protesters assembled on the Stroffolino Bridge, which connects East and South Norwalk, including members of Huddle CT, Indivisible CT, MoveOn, and the ReSisters. Two counter-protesters were present, but the demonstration remained civil.

In New Hampshire, a protest was planned in Portsmouth.

New Jersey saw demonstrations in Newark, Princeton, and Red Bank.
