Rep. Max Miller (R-OH) is facing growing questions about his campaign for a third term representing Ohio’s 7th Congressional District, as allegations of domestic abuse made by his ex-wife have engulfed his reelection campaign.

The controversy intensified after renewed public attention to allegations made by Miller’s ex-wife, Emily Moreno, during their ongoing custody dispute. She has accused Miller of physically abusing her during their marriage and of endangering their young daughter.
