The action being taken, the president said, follows a nine-month investigation by the Department of Commerce, documenting a growing crisis in U.S. steel and aluminium production that threatens the security of the country. NAFTA talks are expected to resume early next month.
"There's a clear rationale for defending our aluminum and steel industries". It's really an assault on our country.
Opposition leader Bill Shorten said he was confident the government was doing everything it can to get the steel tariff exemption and believed it would be successful. He has invited in steel an aluminum workers'.

The president suggested in the meeting with his Cabinet that Australia and "other countries" might also be spared.
"We have a very close relationship with Australia", Mr Trump said ahead of the formal announcement of his tariffs plan.

Disagreement within the White House over the announcement reportedly led to the resignation Tuesday of Trump's chief economic adviser, Gary Cohn.
Trump has been frustrated by the delay, the officials say. "These tariffs will raise prices on so many products that Americans buy every day".
