Transcript for NBA All-Star Game still on schedule to play tonight
pandemic itself, the CDC says the number of people fully vaccinated in the U.S. Is approaching 30 million and the seven-day average of daily cases is about 61,000, that's around what it was its peak last summer. But some states are now easing restrictions with masks coming off. ABC's elwyn Lopez is in Atlanta where there's concern about crowds gathering for tonight's NBA all-star game. There will not be fans in the stands. Good morning, elwyn. Reporter: Will, good morning. The chances of the NBA all-star game taking place this year was slim, it was supposed to take place in Indianapolis, cancelled due to the pandemic, and now it's back on in Atlanta, we're just hours away from showdown. This morning, the NBA all-star game a magnet for out of state fans. Closed to the public with no nba-sanctioned events. Fans are coming to Atlanta for the atmosphere outside the arena. Mounting concerns that this could be a superspreader event. These vaccinated fans flew in from Dallas. This is really a first time we're really getting out and doing something. Reporter: And nationwide, spring break is in full effect. Overnight, in Colorado, authorities say three officers were assaulted with bricks and rocks at a massive street party in Boulder. Fireworks blasting off. People taking to social media saying a car was flipped. Meanwhile, in south Florida, partygoers piling into bars. This weekend kicking off the busiest time for the sunshine state. So we worry we're going to get this huge influx of people, they want to let loose or they want to get out and do things. Now is not the time. Reporter: While in daytona Beach, hundreds of thousands rumbled into town, the annual bike week back for its full run, but this time with restrictions indoors. Capacity capped at 60%. And a mask mandate. If everybody does what they're supposed to do I believe it will be okay. Reporter: "The New York Times" now reporting the highly contagious uk variant accounts for more than 20% of new cases in the U.S., something the CDC has warned about, helix revealing Florida had the highest share. Health experts say the finish line is near but the race isn't over. There are these new variants that are taking hold in communities and you create mixing of populations and travel that will just create more opportunities to stir up outbreaks in different populations and unfortunately, lead to surges in cases. Reporter: Here in Atlanta, police are cracking down on large, non-nba sanctioned events. They're working around the clock, 12-hour shifts, some officers even cancelling their days off. Thank you so much. The pandemic is now a major concern of the U.S. Military, and in a "This week" exclusive interview, ABC's Martha Raddatz asked secretary of defense Lloyd Austin about the battle against the virus. You also said in your priorities that the greatest domestic threat to our security is covid. What can we expect in the coming weeks from the military? We're supporting FEMA requirements and I've been out to visit our troops that are out there vaccinating and it's really remarkable to see not only how our troops feel about what they're doing, but also how the American public responds to the interaction with our troops. We only play a part in this overall effort, but the military has significant capability, capacity, and we can add speed and scale to anything that we endeavor to take part in. Anything that's taken the lives of 500,000-plus Americans, if we can add value to the overall effort we're going to do that. Martha is joining us now. She's hosting "This week." Later on this morning. Martha, good morning to you. Of course, you've covered many wars, armed conflicts all over the world for years, but the pandemic is something entirely different here, how would you characterize the significance of the military's role and the way secretary Austin is approaching it? I think it's extremely there's really nobody better at logistics, which I've seen in conflict Zones all over the world than the U.S. Military, they can deploy quickly to these areas to help get those shots into arms. They can organize, from the National Guard to active-duty military. I've been across the country, I've seen upclose what they do, it's a very important contribution to fighting this pandemic and of course, the military is also fighting it within, they have very strict protocols, secretary Austin's mask was right there on the desk. We were about ten feet apart. They're very stribt -- stribt about it. There's masking in the military, they've had a few outbreaks but pretty well under control over the past year in the military. But they want to do whatever they can to help out and speed up this process. And we've seen some of the teams fanning out across the country. I want to goat back to the covid relief package. Not one Republican senator voted for it. The Democrats had to make some changes to satisfy their own ranks, like senator Manchin. It's the first major legislative win for president Biden, but how does this partisan vote set the tone politically for him going forward? As Mary Alice pointed out, this was supposed to be the easy one. If you can't get any Republicans' support for a covid relief bill in the middle of a pandemic, look out going forward. Now, Joe Manchin really was at the center of the storm, he brought the senate to a standstill for about ten hours, you also have to remember about Joe Manchin, West Virginia, heavily supported Donald Trump and he is a Democrat, has talked about bipartisanship but it doesn't look like they're going to get it at this point. Democrats can't afford to lose one senator on any legislation going forward. Martha Raddatz for us, thanks so much. Stay tuned for "This week" later on this morning. Martha interviews senator Joe Manchin and governor Mike dewine. Plus as you heard, defense secretary Lloyd Austin discusses the latest challenges facing the U.S. Armed forces. That's all coming up on "This week."
