WASHINGTON (Reuters) - The top Democratic lawmaker on a U.S. House oversight panel has sought information from nine oil companies about a media report about "quid pro quo propositions" made by former President Donald Trump, according to a statement from the lawmaker.

In letters to CEOs of companies including Exxon, Chevron and Chesapeake Energy, Representative Jamie Raskin of the Committee on Oversight and Accountability said, "I write to request any information you may have about quid pro quo financial agreements related to U.S. energy policy that were reportedly proposed at a recent campaign fundraising dinner with ex-President Donald Trump."
