This claim was made by Jacqui Heinrich on April 29th, 2025. After investigating into Heinrich's career, she is currently serving as a Senior Whitehouse Correspondent and anchor for FOX News. It may be interesting to note FOX News' generally acknowledged conservative bias, but I personally do not know if Heinrich shares those political beliefs herself.
Upon looking into the more recent news surrounding this claim, I found it to be false. I was able to find an Associated Press article that reported that Amazon will not go through with listing the tariffs affecting their prices on their website. According to the article, this news came shortly after the White House called such an action a "hostile act" (Grantham-Phillips and Boak). It appears that the White House viewed this act by Amazon as an attempted political message to get customers upset about the tariffs taking place, causing those same customers to develop anger towards the political party in power.
