Exactly one month after he took the oath of office, thousands rallied together in New York CIty's Central Park on President's Day to speak out against President Donald Trump's agenda -- many holding signs with bold and unique messages opposing his new administration.
Protesters gathered in the park before marching to Trump's International Hotel and Tower in Columbus Circle where they hoisted colorful signs that said the word "No!" in different languages, condemned the president's Cabinet nominations, and called for Trump's impeachment.
One man held a double-sided sign with two messages. One side read, "Trump Trumps. Bannon Bans. Conway Cons," -- a reference to Trump's inner circle -- while the other side read, "America, urine danger" -- a reference to the more salacious claims made in the unsubstantiated Russian dossier Trump has denied.

Other protesters' displayed signs with messages that attacked Trump's controversial executive orders, such as the pipeline executive order reviving the Dakota Access pipeline, with texts including "Resist," "Revolt," and "Lock him up" -- a spin on the anti-Hillary Clinton "Lock her up!" chant that was popular at Trump's campaign rallies.
Whether written or spoke, many attendees at the rally had harsh words for Trump.
New York resident Colin Robinson, 24, told AOL News he joined the rally Monday because he disagrees with Trump's immigration policy and travel ban.
"Trump's immigration policy and cooperation he has from immigration enforcement -- here in New York City, especially -- [is] the thing that's on the top of my mind right now," Robinson said. "He's ruining lives [and] hurting people. People are going to die."
Monday's rallies arrived amid what has been a flurry of protests from liberal grassroots groups following Trump's entrance into the White House, starting with the Women's March on Washington -- what its organizers intended to be "a bold message" to the new administration -- the day after Trump's inauguration. Opposition has also been voiced on a wide range of issues, including immigration and climate change.
Emily Lewis, 27, another rally attendee, told AOL News that her goals are "to improve the voting process so that everyone can have representation that actually suits their neighborhood. I want to support nonprofits and the political parties that are in favor of fixing gerrymandering."

Janilla Perez, 19, who was one of about 20 members of Movimiento Cosecha -- a group fighting for the permanent protection of undocumented immigrants nationwide -- said her group attended to the rally to show support and spread awareness about their nonviolent movement.
"We're just trying to raise awareness and we're really fighting to show the economic impact that immigrants have on this country because we do basically support this economy," Perez said. "We want to show the country that without us this country wouldn't really run as well as it does."
She also disagrees with the president's views on immigration.
"I don't agree with any of his policies," Perez continued. "The fact that he's purposely putting people against each other and he's using racism and xenophobia as his tactics [is] really upsetting and that's not what this country stands for."
Sister rallies of the "Not My President's Day" rally in NYC were staged in dozens of other cities including Chicago, Washington D.C., Philadelphia and Atlanta to denounce Donald Trump's presidency.
