An NAACP sit-in protest opposing the nomination of U.S. Sen. Jeff Sessions as U.S. Attorney General ended late Tuesday when six people were arrested at Sessions’ Alabama office, CNN reports.

Sessions was nominated in November.

The protesters, who arrived early Tuesday, said they would stay at Sessions’ office until he was no longer the nominee or they were arrested.

Five men and one woman were arrested, including NAACP President Cornell W. Brooks. They face charges of criminal trespass in the second-degree, according to officials with Mobile’s police department.

“We are asking the senator to withdraw his name for consideration as attorney general or for the President-elect, Donald Trump, to withdraw the nomination,” Brooks said Tuesday from Sessions’ office.

Earlier in the day, Alabama NAACP President Benard Simelton said he and 15-20 others were there “conducting business as usual.” The group members vowed to remain until “Sessions meets our demands or the arrest — whichever he chooses.”

The former Alabama attorney general is no stranger to controversy. His appointment to a federal district court in 1986 by then-President Ronald Reagan sank when a former employee of the U.S. Justice Department testified that Sessions had made racist remarks. Sessions denied the allegations.

Sarah Isgur Flores, a spokeswoman for Sessions, said the senator “has dedicated his career to upholding the rule of law, ensuring public safety and prosecuting government corruption.”

“Many African-American leaders who’ve known him for decades attest to this and have welcomed his nomination to be the next attorney general,” Flores said.
