The mayor of McKinney says his 19-year-old daughter has tested positive for the coronavirus. Mayor George Fuller has been critical of Collin County's stay-at-home order for not being strict enough. Fuller's daughter Layla tested positive the virus after first showing symptoms last week. He says it was harder for his daughter to be tested because she's young and not in a high-risk group. Fuller's shelter-at-home order for McKinney, which is stricter than the county's order, now faces a court challenge.
