March 5 (UPI) -- The U.S. House will vote Thursday on a measure to limit President Donald Trump's war powers Thursday after a similar effort failed in the Senate on Wednesday.

The war powers resolution, backed largely by Democrats, would require the president to seek congressional approval to continue military action against Iran.

The Constitution says the authority to declare war lies squarely with Congress. House Speaker Mike Johnson, R-La., has denied that the United States is at war with Iran, saying the military action is "limited in its scope."

"I believe we have the votes to put this down and I certainly pray that's true," Johnson said during a news conference on Wednesday.
