President Donald Trump demanded on Monday that gasoline retailers immediately lower pump prices, warning of "big problems" if they do not, as he pressed companies to move faster after crude oil prices fell from wartime highs.

Trump Demands Immediate Gas Price Cuts "Gasoline Retailers must get their Prices down, IMMEDIATELY," Trump wrote in a Truth Social post.

"There will be no gauging, which is totally illegal.

If Retailers don’t do this, big problems lie ahead!

Start targeting around the $2.50 a Gallon number," he added.
