MONTGOMERY, Ala. — The national president of the NAACP and five others were arrested after staging a sit-in Tuesday at the Alabama office of Sen. Jeff Sessions, the nominee for U.S. attorney general, the civil rights group said.

The organization held the demonstration to protest Sessions’ nomination by President-elect Donald Trump, criticizing Sessions’ record and views on civil rights, immigration, criminal justice reform, and voting rights enforcement.

“We have an attorney general nominee who does not acknowledge the reality of voter suppression while mouthing faith in the myth of voter fraud,” NAACP President Cornell William Brooks said by phone earlier in Tuesday’s protest. Brooks called Sessions a poor choice to lead the U.S. Justice Department.

The sit-in at Sessions’ office in Mobile, Alabama — the city the Republican senator calls home — began around 11 a.m. Tuesday. Demonstrators refused a request by the manager of the building— which includes several other tenants in addition to Sessions— to leave when the building closed for the day at 6 p.m.
