Trump's executive order expands tax-exempt diesel access ahead of US midterms.
Context
What happened: US President Donald Trump signed an executive order to broaden access to tax-exempt diesel, after announcing the move at a rally in Nebraska. The order removes the restriction limiting tax-free diesel to off-road use.
Key numbers: Diesel prices hit a record of about $6.50 a gallon last month. Trump's approval rating was 32% in a Reuters/Ipsos poll.
Why it matters: High diesel prices are seen as a risk to Trump ahead of the midterms, where control of Congress is at stake. The order follows pressure from Trump, who had said he was considering a ban on US diesel exports.
