Nearly a thousand people filled the high school auditorium in the Iron Range town of Virginia yesterday to talk about problems in the nation's steel industry. Mining companies and their workers have banded together, calling on President Bush to use some form of trade sanctions to limit the amount of foreign steel importred to the United States. Federal officials came to Minnesota to gather testimony in their investigation of the industry's troubles. Minnesota Public Radio's Chris Julin was at the hearing, and he has this report.
