and yesterday president biden addressed what he believes the state of covid-19 will be in the future and whether it will stay here in to it country for the long haul. >> no, i don't think covid is here to stay. but having covid in the environment here and in the world is probably here to stay. but covid as we're dealing with it now is not here to stay. the new normal doesn't have to be -- we have so many more tools we're developing and continue to develop, that can contain covid and other strains of covid. the new normal is not going to be what it is now. it's going to be better. >> reporter: so confronting the coronavirus remains the top challenge for the biden administration, as to how the president responds to this, will ultimately determine his performance in office over the course of the next few years. >> all right, arlette i'd say that's right here. i appreciate it. william in frormt baltimore
