(Reuters) -U.S. President Donald Trump on Tuesday blasted an appeal court's decision to temporarily block federal officials from completing a land transfer needed for Rio Tinto and BHP to develop Arizona's Resolution Copper project.

Trump, in a post on Truth Social, called the court - the San Francisco-based 9th US Circuit Court of Appeals - a "radical left court." He said that those who oppose the mine "are Anti-American, and representing other copper competitive countries."
