By Ken Ward Jr. The ranking Democrat on the House committee that oversees worker safety issues is calling for close scrutiny of President Donald Trump's nominee to run the U.S. Mine Safety and Health Administration. Rep. Bobby Scott, D-Va., questioned the record of Trump nominee David Zatezalo and said in a prepared statement that the nation's coal miners "deserve leadership in MSHA who have a demonstrated record of leading by example." "There is abundant data which suggests that the nominee for Assistant Secretary of MSHA has repeatedly failed to abide by basic mine safety standards, and neglected to adequately protect the health and safety of miners for whom he was responsible," said Scott, the ranking minority member on the House Committee on Education and the Workforce.
