Trump disputing CPI data and denying inflation creates market uncertainty over policy credibility.
Context
What happened: At rallies in Arizona and Montana, President Trump disputed the monthly CPI report released earlier that day, saying "we don't have inflation."
Key numbers: CPI showed a near 4% jump from this time last year.
Why it matters: The remarks put the president at odds with the official inflation data released the same day, during his midterm campaign blitz.
