Story highlights Sessions spokeswoman says he is being falsely portrayed

NAACP activists were protesting his nomination as US attorney general

(CNN) An NAACP sit-in to protest the nomination of US Sen. Jeff Sessions as US attorney general ended late Tuesday when six people were arrested at Sessions' Mobile, Alabama, office.

The arrests of five men and one woman included NAACP President Cornell W. Brooks, said Malik Russell, director of communications for the civil rights group. They face charges of criminal trespass in the second-degree, according to Mobile police.

The protesters arrived earlier Tuesday and said they would stay until Sessions is no longer the nominee or they were arrested.

"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 afternoon from Sessions' office.

"In the midst of rampant voter suppression, this nominee has failed to acknowledge the reality of voter suppression while pretending to believe in the myth of voter fraud."
