Fmr. NASA astronaut Cmdr. Scott Kelly raising funds to replace ambulances destroyed in Ukraine

Ten ambulances are destroyed every week in Ukraine as Russia’s war drags on. Former NASA Astronaut Commander Scott Kelly, who is raising funds to replace these lifesaving assets, tells Andrea Mitchell he’s “a big believer in democracy and freedom. And as such, I think it's my responsibility to try to defend it in any way I can and help in this very significant cause.”
