Rep. Max Miller (R-OH) on Wednesday was hit with a lawsuit by his ex-wife over a photo of their toddler that was published online. 

The lawsuit is the latest challenge Miller’s reelection campaign has faced from his ex, Emily Moreno, over allegations that he abused her and their 2-year-old daughter. Miller has rigorously denied domestic abuse claims, saying his former partner, who is the daughter of Sen. Bernie Moreno (R-OH), suffers from “significant” mental health problems.
