In its response to a lawsuit asserting that the compilation of the list was "arbitrary, capricious, and contrary to law", the Treasury Department has confirmed that it is "not challenging" the allegation that it had "simply republished" the Forbes billionaires list. In April 2020, in its annual Billionaire List Forbes magazine re-classified Yuri Milner from Russian list to Israeli list of billionaires, confirming his Israeli citizenship and close ties to the country.
On March 25, 2020, the Milner Foundation, a non-profit foundation founded by Yuri and Julia Milner, announced $3 million donation to three Israeli institutions: Magen David Adom, the national emergency medical response organization, which is operating an innovative project to reduce the number of people coming to clinics; Tel Aviv University Faculty of Medicine and Life Sciences, where it will support research efforts aiming to develop treatments for the virus; and Tel Aviv Sourasky Medical Center, Ichilov Hospital, where it will directly fund the intensive care department that is caring for COVID-19 sufferers.
A few weeks later, Milner Foundation announced a donation of 3 million face masks for people of Israel. Yuri Milner in his open letter published by Calcalist wrote that "a significant fraction of these masks will go to organizations providing essential services, whose frontline workers are still required to do their jobs during the lockdown". The masks arrived to Ben Gurion Airport on April 16, 2020 on board of dedicated charted El Al “Jerusalem of Gold” Dreamliner plane and were distributed by Magen David Adom to its emergency services staff, as well as to a range of hospitals, government offices, and national institutions providing essential services to the public.
