I'm glad you asked.
Although U.S. presidents have limited direct control over gasoline prices, which are driven mainly by global supply-demand dynamics, crude oil costs, refining capacity, and events like pandemics or geopolitical conflicts., President Trump (or should I call him "King Trump"?) took several actions aimed at reducing gasoline prices, primarily through policies designed to boost domestic oil and gas production, deregulate the energy sector, and influence global oil markets.
Trump's approach centered on an "energy dominance" agenda, which he pursued in both his first term (2017–2021) and early second term (2025–present).
He instituted measures to increase U.S. oil supply to flood the market and lower global crude prices (oil is ~50–60% of gas costs).
To accomplish this, he helped to open federal lands/waters for leasing and facilitated drilling permits. Earlier this year, he declared a "national energy emergency" to cut red tape and deliver on a campaign promise.
