President Donald Trump explodes Walmart The country's largest retailer warned this week that it would have to raise prices on Saturday due to tariffs.

"Walmart should stop trying to blame tariffs, which is why prices are raised across the entire chain," Trump wrote in The Society of Truth. "Between Walmart and China, they should say "eat tariffs" without charging any fees to valuable customers.

"We used to see prices rising at such a daunting pace at the rate they came," Walmart Chief Financial Officer John David Rainey said in an interview with CNBC on Thursday.

As the country’s retail giant and largest grocer, Walmart is often seen as a leader in the health of retailers and U.S. consumers.

Renney said he was "happy with the progress made by the (Trump) administration with levels of tariffs announced in early April, but they are still too high." Despite a 90-day probation, he lowered tariffs on Chinese imports to 30%. Commodities from dozens of other countries face 10% of their responsibilities. Walmart imports electronics and toys from China and produces avocados and bananas from Central and South America.

Retailers want to keep their prices below competitors, he said, especially as shoppers seek discounts. To this end, he said Walmart will absorb some higher costs related to tariffs, and he hopes suppliers will absorb some higher costs as well.

Renney said the company will "try to work with suppliers to keep prices low."

Walmart responded to that view on Saturday when asked to comment on Trump's position.

"We have been working to keep prices as low as possible and we won't stop," Walmart said in a statement. "As long as we can bring the reality of smaller retail margins, we will be as low as possible."

Walmart joins a growing number of companies that have seen prices rise or warn that prices are being launched due to tariffs. Microsoft It said earlier this month that it raised the recommended retail price for Xbox video game consoles and some controllers.

Barbie Manufacturer Mattel It was moving production out of China earlier this month, but prices are still expected to rise. and Ford Last week, warning that the prices of certain cars must be raised.

Major US retailers, including Target,,,,, Home Depot and LoweThey are expected to share their views on the impact of tariffs when the results are reported next week.
