No lobbying is necessary, since Chris Wright—like everyone else in Trump's cabinet—is simply abusing his position to enrich himself directly: He made his fortune in the shale gas industry. He founded Pinnacle Technologies in 1992, later led Stroud Energy, and in 2011 founded Liberty Energy, which was valued at $2.8 billion in 2023. As CEO of Liberty Energy, he earned $5.6 million that year.
Wright himself is a billionaire and, in his position, represents only his own interests. The entire U.S. regime is organized this way—it has as little to do with a democratic government as the oligarchy in Russia does.
However, if you're referring to the orange mafia boss: His decisions, too, are obviously not based on lobbying, but simply on outright corruption.
