US President Donald Trump signed an executive order on Monday to ease limits on tax-free red-dyed diesel, a move aimed at saving farmers millions of dollars and lowering the cost of goods.[8116850] Trump's decision comes as fuel prices put pressure on Republican candidates ahead of the November 3 midterm elections, and he will visit Nebraska on Monday to rally supporters and promote his economic record.[8116850][8004481] The change to tax-free diesel, which was previously limited to certain industries, is expected to benefit farmers and truckers who use the fuel, although analysts say it will not benefit those already using tax-exempt fuel.[8116850][8004481]
