Today, we stepped onto the debate stage against Mark Baisley. Colorado needs a fighter who will stand up to the president and put working families first. Baisley would be a rubber stamp for Trump: supporting his illegal war that’s raised prices and voting with MAGA. That’s your choice on Nov 3rd.

The sources consistently report that the Iran war initiated by Trump has driven up gasoline and diesel prices and contributed to inflation, with CBO-based reporting attributing a large share of Q2 2026 inflation to the war.

This claim is about the present, so it is judged as of the day it was checked.

What we found

Supports. CBO-based reporting (Senator Warren press release) states that more than 40% of inflation from Q2 2026 is a consequence of Trump's war, and that the war cost DoD nearly $40 billion.[2][5]

Supports. NPR (Oct 12, 2026) reports gas prices are much higher than before Trump started a war with Iran, and PBS reports voters are frustrated by rising gas prices tied to the Iran war.[3][4]

Supports. American Progress reports national average diesel prices up more than 70% versus before the war, with gas and diesel prices rising in every state; ITEP estimates the war-driven fuel price increases cost Americans over $100 billion.[6][7]

Context. Trump has attributed some price pressure to Ukrainian attacks on Russian refineries and has predicted gas prices would quickly decline, but sources report prices remained elevated, and an energy ceasefire failed to lower prices.[1][8][9]

Context. The claim was extracted from a passage calling the war 'illegal' and describing it as having raised prices; the price-increase element is supported, while legality is outside the sources' scope and was not graded.
