DES MOINES, Iowa (AP) — Two House Republicans in battleground Iowa districts, including one who recently campaigned alongside Defense Secretary Pete Hegseth, changed their position on an Iran war powers resolution, joining with Democrats and a few other dissident members of their party in an attempt to halt President Donald Trump's ability to continue military action without congressional approval.

The shift reflects the political pressure on Republicans before midterm elections that will decide control of Congress. The war remains unpopular and has led to soaring fuel prices.

Reps. Zach Nunn and Mariannette Miller-Meeks voted for the resolution with five other Republicans on Tuesday after previously voting against it.
