Your coronavirus need-to-know: Winston the pug never had COVID; Trump suspends flights from China; Starbucks makes cuts

Massive protests over death of George Floyd have health officials worried about a potential influx of coronavirus cases. In Colorado, Gov. Jared Polis is encouraging everyone who was there to go get a free test

Public health experts said it will take two to three weeks to figure out if the George Floyd demonstrations happening across the U.S. will mean a bump in coronavirus cases. And, they note it would be hard to definitely tie them an increase. (Not only are many states loosening restrictions, many places saw large Memorial Day weekend crowds.)

Meanwhile, there's a dust up over the planned Republic National Convention in Charlotte: President Donald Trump said in a series of tweets Tuesday night that the GOP was looking to go somewhere else, complaining that Democratic North Carolina Gov. Roy Cooper couldn't promise that the event could take place without face coverings.

The coronavirus isn't going away anytime soon. Worldwide, there have been almost 6.5 million confirmed cases and the United States is inching closer to 2 million, according to the Johns Hopkins University dashboard
