Senate Democrats, led by Sheldon Whitehouse and Ron Wyden, have launched an investigation into former President Donald Trump's alleged promise to roll back environmental safeguards in exchange for $1 billion in campaign contributions from oil executives. This inquiry follows reports that Trump offered a 'policies-for-money transaction' to secure financial support for his 2024 presidential campaign. During a recent fundraiser in Houston, which included a lunch event, Trump raised $40 million from oil executives and other donors, marking one of his most profitable fundraising days. At the event, Trump vowed to approve pipeline and power plant projects, aligning with the interests of the oil industry. Texas Attorney General Ken Paxton drew Trump's praise at the Houston event.
