The Centers for Disease Control and Prevention had a contact tracing team ready to go, according to multiple sources, but had not been asked to mobilize, even though White House physician Sean Conley said at a press briefing that his team was working with the agency.

Conley also said he was coordinating with local health agencies, but officials in Minnesota, Ohio and New Jersey, where Trump held events in recent days, said they haven’t heard from the White House and are racing largely on their own to find people potentially exposed to the virus.

White House spokesman Judd Deere said any positive test result on the complex is taken seriously and contact tracing is underway…

One man who was pictured mingling in the front rows of the Rose Garden event, who spoke on the condition of anonymity to discuss private medical details, said he heard from no one from the government but his doctor had emailed him indicating “that Mrs. Trump had asked how I was.”
