US President Trump wear face mask for the first time in public:

So it seems that he is no longer ignoring the hard facts that this pandemic has hit the US and is out of control. Regarding the topic,
By 11:59 p.m. Friday, he will close the bar for the second time this year. A spike in COVID-19 cases led Nevada Gov. Steve Sisolak’s to roll back reopening for businesses like Jackson's, forcing bars without food to shut down.
https://www.rgj.com/story/news/2020/07/10/nevada-bars-closed-las-vegas-casinos-open-governor-sisolak-update/5414497002/ It's really hard to open casinos as gamblers are going to flock and its hard to control the spread despite the many protocols and guidelines.
He finally did it, because he cannot ignore the fact that Covid is making havoc in the US soil and it will not do good if they will keep denying this
his supporters are not wearing their mask, because he is not wearing mask and he is not supporting proper protocol, I guess now Trump is serious in bringing down the infection.
