PANews reported on June 4th that, according to Jinshi, the Republican-controlled U.S. House of Representatives voted to halt the U.S. war against Iran, parting ways with Trump on this unpopular foreign conflict that is increasingly burdening the American people economically. The resolution passed 215 to 208, with four Republican members crossing party lines to vote in favor along with all Democrats. This indicates that concerns about the war are beginning to spread within Trump's own party. The resolution requires Trump to withdraw U.S. troops from hostile actions against Iran unless Congress formally declares war or authorizes the use of military force against the Middle Eastern country. However, the resolution does not force Trump to completely end the conflict and is more symbolic, as the bill still needs to pass the Republican-controlled Senate, and Trump can veto it during the signing phase.

Earlier reports indicated that when asked how he defined a ceasefire, US President Trump stated, "In that region (Iran), a ceasefire means that the fighting and firing have become more moderate. That's true. The ceasefire there is very different from ceasefires in other regions."
