Florida’s top health official was asked to leave a meeting after refusing to wear a mask at the office of a state senator who told him she had a serious medical condition, officials have confirmed.

Florida Senate leader Wilton Simpson, a Republican, sent a memo to senators Saturday regarding the incident at the office of Democratic state Sen. Tina Polsky, asking visitors at the building to be respectful with social interactions. Polsky, who represents parts of Broward and Palm Beach counties, had not yet made public her breast cancer diagnosis.
