Washington (CNN) -- President Barack Obama used a Memorial Day ceremony to say it is time for America to properly welcome home Vietnam veterans and show them and their families the respect and gratitude they deserved but didn't receive decades ago. "You came home and sometimes were denigrated when you should have been celebrated," Obama said beneath a scorching sun at the Vietnam Veterans Memorial. "It was a national shame, a disgrace that should have never happened. That's why here today, we resolve that it will not happen again." The event, which launched a 13-year Vietnam War 50th anniversary commemoration, was the culmination of a day of somber events on the annual holiday honoring America's war dead.NEW: President Obama calls the denigration of Vietnam veterans a "national shame""America will be there for you," Obama tells veterans and their familiesMemorial Day launches a 13-year commemoration of the Vietnam War's 50th anniversaryObama lays a wreath to the fallen at Arlington National Cemetery

WNBA star Glory Johnson is speaking out to set the record straight about the highly-publicized end to her marriage with fellow basketball player Brittney Griner after just 28 days. The 24-year-old Tulsa Shock player and Griner, who plays for the Phoenix Mercury, filed for an annulment earlier this month, just one day after Johnson announced she was pregnant by a sperm donor. In a tearful interview with ESPN last week, Griner, also 24, said that she felt pressured into getting married and was having negative thoughts about the union leading up to the big day. But Johnson says that wasn't the case, and that Griner's change of heart was sudden and surprising.Phoenix Mercury basketball player Brittney Griner filed for an annulment to end her marriage to Tulsa Shock player Glory Johnson on June 5The day before, Johnson announced she was pregnant via a sperm donation on InstagramIn an interview on Friday, Johnson said Griner's sudden change of heart about their marriage and child took her by surpriseJohnson spoke out, after Griner gave a tearful interview saying she felt she had been pressured into the marriageJohnson says she did not pressure Griner and that they were both active participants in trying to start a family
