Jack W. Gravely appears poised to resign as executive director of the Virginia State Conference of the NAACP, the Free Press has learned.

Mr. Gravely, a radio talk show host and former state NAACP executive director who returned to the leadership position in April 2015, was not immediately available for comment.

However, a source close to events said Mr. Gravely is expected to call a news conference Friday, June 24, to announce his decision to leave, ending his efforts to rebuild the slumping civil rights group.

According to the source, Mr. Gravely is ready to depart because of strained relations between him and several key state executive board members, including the current president, Linda Thomas of Caroline County, and James E. Ghee of Farmville.

“Jack feels he has been relegated to being an office boy,” the source said, describing the situation as a struggle over Mr. Gravely’s ability to operate independently.

Reached Wednesday, Ms. Thomas said she was unaware of any resignation plans. “I would be saddened and disappointed if that is Mr. Gravely’s intention,” she said, declining further comment.

Mr. Gravely, also host of “The Jack Gravely Show,” on WLEE 990 AM, was brought on to revive the state group.

The group floundered for more than a year after the state board, led by then- President Carmen Taylor of Hampton, dismissed the group’s longtime executive director, King Salim Khalfani, in February 2014.

Mr. Khalfani’s departure left the state office on the campus of Virginia Union University without any employees. The door was locked and the phone went unanswered for months.

Mr. Gravely initially planned to stay just a year until a new executive director could be hired. He continued to serve amid still unresolved discussions with the board about extending his contract.

Under Ms. Thomas, the board recently made changes, including severing ties with Rodney Thomas, no relation to Ms. Thomas, who was hired more than a year ago to provide lobbying services for the organization at the Virginia General Assembly.

This has been Mr. Gravely’s second stint as executive director. He originally held the post for nearly 10 years, from November 1976 to January 1985.

He then moved to Arlington County to work as a special assistant to the county manager and then held positions at National Public Radio, the national NAACP and the Federal Communications Commission before returning to Richmond.

He started his talk show on WLEE in 2008. He earlier had a talk show on WRVA radio that ended in 2002.
