judy: please pick up on that, ben ginsberg. do you see as an appropriate remedy at the federal level for what concerns you? ben: there will always be concerns about federally legislative elections on the state and local level. but there are parts of the bill, of h.r.1., that could be done, but the democrats are making a huge tactical error, if they really care about these election situations and even about the voting rights situations, in having so many other provisions in this bill. you talked before about how republicans are trying to tilt election results by the state that is true. -- state legislation. that is true. but the democrats are trying to do the same thing in s.1 through a number of provisions that are just designed to give them a political advantage. so, if they actually want to deal with the voting issues, it's time to kind of do the obvious and concentrate on those issues and strip away the other provisions. judy: we are just about out of time. bob bauer, do you agree with th, that that's whatemocrats are doing?

bob bauer, ben ginsberg, we appreciate it. >> thank you very much. >> woodruff: as we reported earlier, president biden is expected to announce tomorrow that the united states will purchase 500 million more doses of covid vaccines that will be donated to the world's poorest countries and the african union. this announcement comes as the leaders in the private sector are stepping up their efforts to aid in the pandemic response. amna nawaz explains. >> nawaz: in one of the largest private-sector donations of its kind, t mastercard foundation announced they'll give $1.3 billion over the next three years to vaccinate 50 million people on the continent of africa. fewer than 2% of the people who live in africa have gotten a single dose of the vaccine yet. that's far lower than many of the wealthiest countries and well below the global average of 11%. ajay banga is the executive chairman of mastercard, and he joins me now. ajay, welcome to the "newshour". thank you for making time. $1.3 billion, one of the largest gifts in the entire pandemic. why this much and why now? >> thank you for havi
