YORK, Pennsylvania, Aug 19 (Reuters) - Republican

presidential candidate Donald Trump on Monday will reiterate he

would block Nippon Steel's ( NISTF ) planned purchase of U.S.

Steel and move to rescind Biden administration power plant

pollution rules.

Trump in February had signaled he would move to block the

deal. Trump will tell workers in York, Pennsylvania that if

elected he "will stop Japan from buying U.S. Steel," according

to prepared remarks.
