The family of Alex Pretti says they're still searching for answers seven months after federal immigration agents in Minneapolis shot and killed the 37-year-old in January. In an interview on ABC's "Good Morning America," Pretti's father called President Donald Trump "unpresidential" over his response to the killing, as the family says they haven't heard anything from Trump administration officials about the incident. CNN is reaching out to the White House for comment. #alexpretti
