Thousands turn out for anti-Trump protests across U.S.

Thousands of demonstrators across the U.S. turned out to challenge Donald Trump in a Presidents Day protest dubbed "Not My President's Day."

The events on the federal holiday Monday didn't draw nearly as many people as the million-plus who thronged the streets following the Republican president's inauguration a month earlier, but the message was similar.

Thousands of flag-waving protesters lined up outside Central Park in Manhattan. Many in the crowd chanted "No ban, no wall. The Trump regime has got to fall." They held aloft signs saying "Uphold the Constitution Now" and "Impeach the Liar."

A rally in downtown Los Angeles also drew thousands. 

Demonstrators there called attention to Trump's crackdown on immigration and his party's response to climate change and the environment. Organizers said they chose to rally on the holiday as a way to honour past presidents by exercising their constitutional right to assemble and peacefully protest.

In Chicago, several hundred rallied across the river from the Trump Tower, shouting "Hey, hey, ho, ho, Donald Trump has got to go." 

Rebecca Wolfram of Chicago, in her 60s, said concerns about climate change and immigrant rights under Trump prompted her to start attending rallies.

"I'm trying to demonstrate as much as possible until I figure out what else to do," said Wolfram, who held a sign that said "Old white ladies are really displeased."

Several hundred demonstrated in Washington, D.C. Dozens gathered around the fountain in Dupont Circle chanting "Dump Trump" and "Love, not hate: That's what makes America great."

Dozens marched through midtown Atlanta for a rally named with a Georgia flavour: "ImPEACH NOW! (Not My) President's Day March."

Hundreds of protesters chanting "This is what democracy looks like" marched through Salt Lake City.

A small but unruly group of protesters faced off with police in downtown Portland, Ore.

The Oregonian/OregonLive reported that police confronted the crowd in front of the Edith Green-Wendell Wyatt Federal Building and took some people into custody.

Hundreds of Trump opponents and supporters turned out in Rapid City, S.D.

A larger anti-Trump faction stood on a street corner as part of a "Not My President" protest, similar to other demonstrations being held across the country. A group supporting the president lined up on a different corner at the same intersection.

The Rapid City Journal reported the anti-Trump protesters held up posters including some reading, "Make America Think Again" and "Build bridges, not walls." Supporters of the president waved American flags and held signs saying "God Bless our Presidents; Go Trump" and "Veterans for Trump."
