President Trump called Rep. Max Miller on Monday and expressed concern about the Ohio Republican’s reelection campaign, according to CBS News. The call came as Miller’s campaign faces serious allegations involving his ex-wife, Emily Moreno, and their 2-year-old daughter.

The controversy has disrupted Miller’s bid for another term in Congress. The allegations have put fresh pressure on the congressman at a sensitive point in the campaign and added a new political challenge in Ohio.

Based on the available report, the concerns raised in Trump’s call were tied to the potential political fallout from the accusations. The claims against Miller involve accusations that he assaulted Moreno and their young daughter, issues that have quickly become central to the campaign story.

The developments place Miller under increasing scrutiny as the race moves forward. With Trump weighing in directly, the situation appears to have become both a legal and political test for the Ohio lawmaker’s reelection effort.
