From the Washington Post:
An aide who saw Trump late Thursday said he seemed normal and did not show any symptoms, though he was aware of Hicks and her condition. Hicks is showing symptoms, officials said. Aides said all of his political events will be cancelled for the foreseeable future.
After White House officials learned of Hicks’ symptoms, Trump and his entourage flew to New Jersey, where he attended a fundraiser and delivered a speech. Trump was in close contact with dozens of other people, including campaign supporters at a roundtable event.
