Republican Rep. Glenn Grothman of Wisconsin is pointing to President Donald Trump’s public behavior as a contributing factor in the Republican Party’s losses in Tuesday’s midterm elections, arguing that the president’s remarks are alienating voters and damaging the party’s image. Grothman also called on people close to Trump to intervene and encourage him to change his approach.

Speaking Wednesday during an interview with Wisconsin radio station KFIZ, Grothman said he believes the administration has capable Cabinet members but argued that Trump’s public comments have become a political liability for Republicans.

“I think what it came down to is, you know, President Trump who I think has a very good Cabinet, but he sometimes talks inappropriately, not very presidential,” Grothman said. “I talk to a lot of people and I’ll tell you, it turns people off.”

Grothman’s remarks add to growing disagreements within the Republican Party over the reasons behind the midterm defeat, which cost the GOP control of both chambers of Congress. While some Republicans have pointed to the economy, the war in Iran and the party’s campaign strategy, Grothman focused on the president’s conduct and the effect it has on voters who may otherwise support Republican candidates.

The Wisconsin congressman has raised similar concerns before. In an October interview, he said Trump’s behavior was hurting the Republican brand and warned that voters unhappy with the president could express their frustration by voting against Republican candidates. He specifically criticized Trump’s comments about renaming Lake Ontario and the Kennedy Center, as well as what he described as the president’s tendency to brag rather than project humility.

Grothman’s latest comments also come as Trump has rejected the idea that he was responsible for the party’s election losses. Speaking to reporters Wednesday, Trump argued that Republicans would have performed better if his name had appeared on the ballot, pointing to the large crowds at his campaign rallies and saying the enthusiasm had not transferred to GOP candidates.

Vice President JD Vance offered a different explanation, identifying the war in Iran as a major reason for the Republican defeat. Trump later described Vance’s assessment as largely true, acknowledging that the conflict contributed to higher gasoline prices while maintaining that his decision to pursue it was necessary.

The competing explanations reflect an emerging debate among Republicans over whether the party should change its policy priorities, campaign strategy or approach to the president as it prepares to operate in the minority. Grothman’s call for intervention suggests at least some GOP lawmakers believe Trump’s public conduct itself has become an obstacle the party must address.
