@cspanofficial: The parents of Alex Pretti, the Minnesota nurse fatally shot by immigration agents in January, accused the federal government of withholding information about the investigation into their son's death. "The federal government went on TV and lied about Alex. They tried to slander his memory to cover up their crime. Not only was it wrong, it was shameful, unfair, unacceptable," his mother, Susan Pretti, said at a news conference Tuesday. "We want to clear our son's name. We want the world to understand who Alex really was. We want our son's killers brought to justice once and for all." #cspan #ice #minnesota #alexpretti
