Reporter on capitol hill today, dr. Anthony fauci gave the country some hope, telling lawmakers he is cautiously optimistic that there could be a laccine by the end of this year.

Reporter testing czar Admiral Brett Giroir admitted that the nation was not meeting the benchmark for testing, and he urged americans to take responsibility for keeping themselves safe. We cannot test our way out of this or any other pandemic. Testing does not replace personal responsibility. Reporter today, the National Institutes of health announced they are ramping up, investing nearly 250 million in new technologies, which they say will significantly increase covid19 testing by millions per week.

Right now, were anticipating some Tropical Storm conditions. Reporter look, Hurricane Season is already well ahead of normal in terms of how many storms there have been. Tonight, behind isaias, there are two more storms that are forming. And i have to tell you, with florida hemorrhaging resources related to the pandemic, norah, the last thing people in florida want to hear about is a hurricane. Odonnell yeah, i understand that. David begnaud, thank you. Well, tonight, its not just florida, but much of the east coast that is nervously watching the track of this hurricane. Streets and homes and businesses were left flooded in puerto rico. In some areas, there were mudslides. And now, millions along Floridas Atlantic coast are bracing for its impact. Chief weathercaster lonnie quinn has the storm track for us. Good evening, lonnie. Reporter good evening, norah. All right, we have the most recent information from the National Hurricane center, and a lot has changed from what i was talking about earlier this morning on cbs this morning. Theres good news and theres bad news, okay. The good news is, the storm has actually gotten weaker. We had winds blowing earlier at 80 miles per hour. Its down now to about 75. Maybe a little bit of interaction with the bahama islands is providing friction. But the track is providing some bad news. Its now closer to the u. S. Shoreline. In fact, there are a couple of landfalls possible maybe one in florida tomorrow, another is possible along the carolina coast. And then its even possible to have a landfall somewhere around new york city or out on long island by the time you get to tuesday or wednesday. The wind field has changed, as well. Obviously, as the hurricane shifts further to the west, it brings the bigger winds with it, as well. But look at this picture, norah. Notice that red dot. That was where the heaviest winds were. Its much heavier on the eastern side of the storm. The side that is away from land. But still, you have Tropical Stormforce winds expected vero beach, down around boca, some time this weekend. So, its going to get interesting out there. We will deal with this a number of days as it travels up the eastern seaboard. Norah. Odonnell lonnie with the latest information from the track just reported. Thank you. Tonight, a vital lifeline for more than 25 million americans is about to go away. Since march, unemployed workers have received an extra 600 a week. Now closeddoor talks to extend the benefit appear to be going nowhere. Cbs nancy cordes joins us now from capitol hill. So, where do those negotiations stand . Reporter well, norah, the House Speaker and the white house chief of staff are meeting again tomorrow, but they both said that theyre still very far apart, both on Unemployment Benefits and on the broader rescue package that will include funding for schools and testing and local governments, and so on. So, yes, it does appear that this 600 federal unemployment benefit is going to expire, at least for a while. Now, republicans and the white house have been offering a few shortterm extension options maybe for a week, perhaps a few months at a reduced rate to give the two sides more time to talk. But democrats are holding out. They say americans need more money, and they need more certainty that these checks will keep coming until january. Odonnell nancy, congress has known about this deadline for months because they set the deadline themselves, right . Reporter right. And part of the problem is that Republican Leaders deliberately waited until we got very close to the deadline because they felt it would give them more leverage in negotiations. But they may have misjudged how much opposition there would be among their own members to extending this unemployment benefit, especially at the current 600aweek level. And, so, theyre now essentially engaged in two negotiations one with democrats and one with their own party. And that makes things more complicated. Odonnell really complicated. Nancy cordes, thank you. Tonight, we are learning new details about what could be one of the deadliest Marine Training accidents in u. S. History. One marine is dead and eight Service Members are missing after their Amphibious Assault vehicle sank while on a Training Mission off the coast near san diego. Heres cbs david martin.

Reporter yesterday evening, off san clemente island, an a. A. V. Carrying 15 marines and one sailor was returning to its mothership when it went dead in the water and began to sink. Inside, they would have been crammed together and probably nauseous from diesel fumes and wave action. Its extremely claustrophobic and and just unpleasant. Reporter former marine nate eckman recalls the a. A. V. All too well. I remember us saying we would have rather hiked the distances we had to than to be carried by an a. A. V. Reporter a marine officer said that last nights sinking could be the worst a. A. V. Training accident ever. All a. A. V. Training has now been suspended. David martin, cbs news, the pentagon.

Today, House Speaker nancy pelosi accused President Trump of trying to delegitimize the election. He wants to cancel the election, postpone the election. Really .
