President Donald Trump levied a fresh threat to countries that have yet to announce trade deals with the U.S. with just four days to go before his new August 1 'doomsday' deadline.

Trump skirted over the details when questioned about highly anticipated price hikes for steel, aluminum and pharmaceuticals, with vast economic impacts at stake in each sector.

Then he was asked about what his tariff would be for the remaining countries that haven't landed a deal.

'I would say it'll be somewhere in the 15 to 20 percent,' he said to reporters at his Turnberry, Scotland, golf course sitting next to British Prime Minister Keir Starmer.

'Probably one of those two numbers,' Trump added, leaving himself some flexibility.
