Protesters associated with the environmental group Greenpeace scaled a 270-foot crane in downtown Washington D.C. on Wednesday morning, according to police.
Officers were first called to the area of 15th and L streets, where three unauthorized people were at a construction site blocks from the White House, Capt. Robert Glover of the Metropolitan Police Department said, according to the Associated Press.
The construction site was at the old Washington Post building.
The three individuals attached themselves to the crane and climbed it. They were later joined by four other protesters on the crane, making seven in total.
Glover said the demonstrators are believed to be with Greenpeace and told police they are exercising their First Amendment rights.
They hung a large yellow banner on the crane near the White House that read "Resist" in black letters, in an apparent protest against Donald Trump's presidency.
Their actions came one day after the Trump administration "moved to delay implementation of at least 30 environmental rules and froze new Environmental Protection Agency contracts and grant awards," the AP noted.
The protesters scaling the crane caused police to shut down streets in the nation's capital.
Traffic stalled after 15th St. between L and M St., NW was closed, as was L St. between L and M St., NW for what police called "protest activity," ABC7 reported.
