Trump says he will make a major announcement on diesel

Trump says he will soon share important news about diesel, but has not explained what it is.

Diesel averaged $6.28 a gallon in the US on Oct.

9, after reaching a record $6.53 on Sept.

22.

High fuel prices affect drivers and the cost of moving goods.

The US has also temporarily allowed some off-road diesel to be used on roads and delayed its federal tax until year-end.
