PHILADELPHIA (CBS) — Former New Jersey Gov. Chris Christie has a warning for people about COVID-19 — wear a mask. Christie was one of many people who chose not to wear a mask while visiting the White House, which at one point became a hotbed of infection.

In October, Christie says he spent seven days in an intensive care unit before recovering from COVID-19.
