During today's press conference in which he declared the new coronavirus to be a national emergency, President Trump announced that Google was developing software that would be central to the US' containment strategy. Trump, along with Dr. Deborah Birx, a key official in the administration's Coronavirus Response Coordinator, said that Google's Web portal would be central to the process of helping US residents take advantage of a promised expansion of the country's testing capacity.

Two hours later, however, Google communications felt compelled to issue a statement saying that nearly everything about this is either not quite right or badly mistaken. The portal is being done by a different company, and isn't even ready for testing in the single location it's planned for: California's Bay Area.
