What they're saying: "I was the WH Ebola Response Coordinator in 2014-15," Klain tweeted.

A poor response to the coronavirus could be politically devastating for President Trump, and so far his administration has given the strong impression that it’s still scrambling as the risk of a pandemic mounts.

Why it matters: There’s only so much any president can do to stop a virus from spreading, and for now the coronavirus is still very much under control within the U.S. But if the disease get worse in the months ahead, and if the administration seems to be caught off guard, that spells trouble for public confidence in Trump.

Many U.S. hospitals have been stocking extra supplies and refreshing disaster preparation plans over the past month in the event the coronavirus becomes more prominent domestically.

President Trump announced at a press briefing Wednesday evening that he'll be putting Vice President Mike Pence in charge of leading the administration's response to the coronavirus.

A person in California who hadn't traveled to a country impacted by the novel coronavirus nor had any known contact with anyone infected by the virus has tested positive to COVID-19, the CDC said in a statement.

Why it matters: Per the CDC, "It's possible this could be an instance of community spread of COVID-19, which would be the first time this has happened in the United States. Community spread means spread of an illness for which the source of infection is unknown." However, the patient may have "been exposed to a returned traveler who was infected," the CDC noted. "At this time, the patient's exposure is unknown," it said.
