the first lady doctor joe biden is on a four-day trip to eastern europe. her european ship has been timed around mother s day on sunday, an occasion that might feel vastly different for ukrainian mothers and children this year. she spoke about that with an exclusive interview with msnbc s symone center. like most americans that watch the tv, we saw all the mothers gathering their children, kissing their husbands get by and then leaving the country. it was just so emotional, just so heart-wrenching. mother s day was coming up and i said to joe, i am going to go stand with the mothers of ukraine. they have to know that we are standing with them. they have been my inspiration because if they can be strong, than i can be strong for them.
