Citizens for Responsibility and Ethics in Washington taking very serious look' at whether Mar-a-Lago meeting justifies legal action

A powerful watchdog group that has been at the forefront of efforts to hold Donald Trump accountable for constitutional violations is investigating whether his Mar-a-Lago meeting with oil company executives last month merits legal action.

Citizens for Responsibility and Ethics in Washington (Crew) has told the Guardian that it is investigating the dinner at Trump's club with more than 20 oil and gas company executives. Trump asked them for a $1bn presidential campaign contribution, while at the same time vowing to undo Joe Biden's restrictions on natural gas export permits, oil drilling and car pollution, the Washington Post reported.
