HAMMOND, United States: Hillary Clinton took her bid for the White House to the depressed steel belt of Indiana on Tuesday, pledging to revive beleaguered manufacturing and hold China accountable for trade abuses. The Democratic frontrunner jetted in from Pennsylvania, as it and four other northeastern states voted in the latest round of primaries expected to hand the former secretary of state more big wins over her rival Bernie Sanders. On Tuesday, she had her head down in the Indiana town of Hammond, where she was given a guided tour of Munster Steel, a family business founded in 1957 that uses only American steel in production. She met workers and was given a tutorial on how particular machines were operated. The company specializes in making bascule bridges.
