Senate Democrats are pushing for an end to a campaign by the Trump Administration to seize $20 billion in funding Congress approved for efforts to reduce greenhouse emissions.

EPA Administrator Lee Zeldin has sought to rescind the funds appropriated in the 2022 Inflation Reduction Act for projects involving retrofitting homes to use less energy and sponsoring off-grid renewable energy projects, according to Reuters.

Last week, Democratic Senators Edward Markey, Sheldon Whitehouse, Chris Van Hollen and Bernie Sanders sent a letter asking the Justice Department’s Inspector General to investigate the resignation of a federal prosecutor being pressured to criminally investigate a contract former President Joe Biden’s EPA awarded using funds from the Inflation Reduction Act, Reuters reported. The prosecutor, Denise Cheung, resigned last week.

A separate letter signed by nine Democrats on the Senate’s Environment and Public Works Committee took aim at Zeldin’s social media campaign attacking the climate funding.

“Your announcement is the latest example of the Trump Administration and its government efficiency 'experts' using unfounded claims of waste, fraud, and abuse as a smokescreen to ignore congressional spending authority and ignore court orders in order to freeze or terminate programs designed to reduce carbon pollution,” the letter stated.
