Washington (CNN) First lady of Virginia Pam Northam "did not focus on black students" when she handed cotton to African-American children on a tour of the governor's mansion and asked them to imagine being slaves in the fields, according to several students who participated in the tour and their parents who spoke to The Washington Post.

The report comes several days after CNN and other outlets, including the Post, reported that Leah Dozier Walker, an employee at the Virginia Department of Education, wrote to Pam Northam's office alleging that while on a tour for state Senate pages, the first lady spoke in the mansion's kitchen cottage -- where enslaved African-Americans were forced to work -- and gave black pages, including Walker's eighth-grade daughter, pieces of cotton.

After Walker's letter became public last week, Northam said in a statement that she regretted causing anyone anguish, stressing that the cottage provided key context to the governor's mansion tours, and that she had conducted the same tour for all visitors.

Walker did not provide a comment to CNN on Monday, and Ofirah Yheskel, a spokeswoman for Northam's office, said that Northam has nothing to add beyond her original statement.

On Friday, the Post, citing accounts from 10 pages given either directly to the paper or through the page's parents, said the pages claimed the first lady "conducted their tours with sensitivity and with no special focus on the black pages." The pages were part of a larger group of about 100 teenagers who toured the mansion in late February. Four of those who spoke to the post were in the group with Walker's daughter and the rest were part of different groups.
