Late Thursday, Minnesota Sen. Amy Klobuchar told FOX 21 more than 400 Northshore miners were back on the job in Silver Bay and Babbitt, which is sooner than expected.

"We pushed so hard to get the administration to start taking this steel dumping seriously and start putting inspectors on the ships and put these tariffs on,” said Klobuchar.

Cliff’s Natural Resources’ facilities in Silver Bay and Babbitt will be fully staffed by early next week, according to Klobuchar.

“They’re starting to process some of the ore. We actually walked right by the furnace and saw some of the pellets with my very own eyes. It's not a mirage. So it's happening,” Klobuchar said.

Klobuchar said strong tariffs were put in place and the Obama administration took action to show these types of results in the form of bringing back American mining jobs.

“Then those foreign companies actually get the message that they’re going to get in trouble and that they’re going to have to pay 2 to 300 percent tariffs -- and they slow down shipping in illegal products,” Klobuchar said. “I've always said our workers can play on an even playing field if it’s an even playing field.”

But all this said, Klobuchar believes a total success has not been reached because the Iron Range is still severely hurting with laid-off minters there.

"This is just the beginning. There are still thousands of workers that are laid off across the range. So we can't declare success until everyone is back to work.”
