Emily Moreno, the daughter of Republican Sen. Bernie Moreno, filed legal papers Thursday against her ex-husband, Ohio Rep. Max Miller, according to documents filed in Cuyahoga County Court. U.S. Rep. Max Miller and his ex-partner Emily Moreno are locked in a bitter custody battle. “The recent reports of domestic violence and child abuse against Representative Max Miller are deeply disturbing and Congress can’t ignore them. Allegations of violence against women and children have to be met with the utmost seriousness,” the lawmakers wrote. According to the court filings, law enforcement opened an investigation after Miller’s daughter broke her collarbone in unexplained circumstances.
