Kaine's wife, Anne Holton, no stranger to political stage

GREENSBORO, N.C. (AP) — Anne Holton first stepped into the spotlight in 1970 as a white student enrolling in a predominantly black middle school in Virginia's capital. The pre-teen was part of a push by her father, then Virginia's governor, for school integration.

Decades later Holton is stepping onto an even bigger stage as she works to get Democratic nominee Hillary Clinton and Holton's husband, Virginia Sen. Tim Kaine, elected to the White House.

Holton is a Harvard Law graduate, former judge and former state secretary of education. She has begun campaigning solo for Clinton and is expected to stay on the campaign trail, both with her husband and by herself, through Election Day.

Her focus is promoting Clinton's plans for education, foster care reform and other issues.
