Republican Rep. Max Miller has insisted he will stay in his race for reelection, despite claims of domestic abuse from his ex-wife and a statement from his former father-in-law, Ohio Sen. Bernie Moreno, that the congressman “should not serve” in Congress.

The controversies surrounding Miller, who represents a district in eastern Ohio, threaten to jeopardize his chances of winning what was once thought to be a safe GOP seat, and could imperil Republicans’ chances of maintaining control of the House after this year’s midterm elections.

Here’s what to know about the controversies that have surrounded the Republican congressman and his relationship with his ex-wife.

Miller married Emily Moreno, the daughter of now-GOP Sen. Bernie Moreno, in 2022 at the Trump National Golf Club in New Jersey, the same year Miller was elected to Congress. They had a daughter in 2023. The next year, Miller filed for divorce, and it was finalized in 2025.

Moreno’s father, Bernie Moreno, meanwhile, was elected to the Senate in 2024.
