WASHINGTON, Oct. 23--Herbert Brownell Jr. resigned today as U.S. attorney general. He said the settling of federal policy in the Little Rock school integration dispute freed him to return to private law practice.

The White House said President Eisenhower accepted the resignation and will appoint Dep. Atty. Gen. William P. Rogers Jr. to the Cabinet post. Rogers is a close friend of Vice President Nixon.

By his resignation, Brownell avoids a prospective series of trips to Capitol Hill in the next session where he would come face to face wiht angry Southern critics.

However, he told his news conference that Southern criticism "did not enter into my calculations at all."
