President Donald Trump delivers a prime-time address Wednesday to Americans on the Iran war as his approval ratings plummet below 40 percent.

The remarks mark Trump's first formal national speech on Iran since launching the war a month ago. Recent polling shows disapproval climbing above the mid-50s as voters sour on both the war and its economic fallout.

Trump claimed a major breakthrough Wednesday, saying Iran's president sought a ceasefire. Iran's foreign ministry immediately denied the claim.

The president has said he can see the war winding down within three weeks while threatening escalation, including targeting civilian energy infrastructure. Gasoline prices have surged above $4 per gallon for the first time in years, weakening consumer confidence and dragging down Trump's economic standing.
