July 29 (Reuters) - A major U.S. refining trade group sent a list of complaints about the Trump administration's handling of biofuel policies to top Republican lawmakers, representing the first rift between the oil industry and the White House since President Donald Trump began his second term, according to a letter seen by Reuters.

The letter from the American Fuel and Petrochemical Manufacturers underscores a growing divide between oil producers and refiners in the nation's capital, a once unified club that has split in recent years over the nation's biofuels policy.

Integrated oil majors like ExxonMobil XOM.N and Chevron CVX.N have used their large financial resources to invest in biofuel production while independent refiners like PBF Energy PBF.N and CVR Energy CVI.N complain that farm-friendly policy has created onerous costs that threaten plants.

AFPM did not respond to a request for comment.
