Why energy will have a starring role if Democrats take Congress

President Trump's energy policies and investment deals could become major targets of Democratic investigations if the party wins control of either chamber of Congress. Why it matters: Congressional probes could expose new details about the administration's dealings with major companies and foreign governments. What they're saying: House Democrats are likely to take a "shotgun" approach of "throwing everything out there and then seeing what sticks in the realm of popular opinion," TD Cowen analyst John Miller said via email. Democrats will be looking for agencies that exceeded their authority, deals involving administration officials' families, or both, Miller said. The big picture: Scratch the surface of Democrats' biggest potential oversight targets, and energy is everywhere. Russia. Trump's dealings with Moscow will again be front and center — and so will the energy dimension. Democrats in both chambers are likely to investigate Trump's diesel deal with Moscow, which they claim violates a 2022 law barring imports of Russian fuels. The inquiries could also extend to U.S. banks and ports, which lawmakers have already warned could face congressional investigation. Venezuela. "We expect Venezuela to be the subject of a number of inquiries," RBC Capital Markets analysts said in a note. Democrats have already raised questions about whether any oil companies knew about plans to depose Nicolás Maduro. Investigations could also examine the legality of the Pentagon's 35% stake in the corporate parent North American Blue Energy Partners and the terms of the deal, the note states. The Iran war. High gasoline and diesel prices give Democrats another reason to scrutinize the decision to attack Iran, especially if pain at the pump persists. Sens. Sheldon Whitehouse (D-R.I.) and Elizabeth Warren (D-Mass.) have already pressed major oil and gas companies about their profits during the conflict. AI and data centers.
