Protesters on Thursday demonstrated against Supreme Court Justice Neil Gorsuch as he headlined his first speech in Washington, D.C. at the Trump International Hotel.
CNN reported that several liberal groups planned on targeting the event as it was held at President Trump's hotel, a property that they say presents a possible violation of the Constitution.
Critics argue that Trump has potentially violated the Constitution's Foreign Emoluments Clause - which prevent the president from getting paid by foreign governments with the approval of Congress - by hosting such entities at his hotel.
CNN reported that People for the American Way, Planned Parenthood Federation of America and NARAL Pro-Choice America were among the groups who planned on demonstrating against Thursday's event.
The invite-only event celebrates the 50th anniversary of the Fund for America Studies, a conservative group who said it booked the venue before Trump entered office or nominated Gorsuch to America's highest court.
"We chose the venue, [and] we had no political agenda," spokesman Steve Slattery said. "It's just a nice hotel and a new venue for us."
"We were looking for a speaker, [and] so we thought, 'let's invite Justice [Antonin] Scalia's replacement,'" he added of Gorsuch's selection.
