Democratic presidential candidate Sen. Kamala Harris calls on Gov. Ralph Northam to resign over his racist yearbook photo.

Harris tweeted: “Leaders are called to a higher standard, and the stain of racism should have no place in the halls of government. The Governor of Virginia should step aside so the public can heal and move forward together.”

Julian Castro, also a presidential candidate, called for Northam’s resignation. The NAACP is also calling on Gov. Northam to resign.

Gov. Northam issued a statement apologizing for the “racist and offensive ” photo but stopped short of stepping down. CBS News also uncovered a photograph in the yearbook at Virginia Military Academy that had the nickname “Coonman” under his photo.
