At a meeting with steel and aluminum industry CEOs, President Donald Trump announced March 1, 2018, that he would impose tariffs of 25 percent on imported steel and 10 percent on imported aluminum.

"You're going to see a lot of good things happen," Trump said. "You will have protection for the first time in a long while, and you're going to regrow your industries."

Trump said he would sign the tariffs into effect the following week.

That has yet to happen.

Press Secretary Sarah Huckabee Sanders told reporters March 5 that "in terms of the specifics of what it looks like, I'm not going to get into that right now because those things are being finalized."

The same day, House Speaker Paul Ryan pushed back against tariffs.

"We are extremely worried about the consequences of a trade war and are urging the White House to not advance with this plan," said Ryan spokeswomen Ashlee Strong in a written statement. "The new tax reform law has boosted the economy and we certainly don't want to jeopardize those gains."

Tweets from Trump hinted that the final rules might exclude Canada and Mexico.

"Tariffs on steel and aluminum will only come off if new and fair NAFTA agreement is signed," Trump tweeted March 5.

Commerce Secretary Wilbur Ross also spoke of flexibility.

"We're not looking for a trade war," Ross said on CNBC March 7. "We're going to have very sensible relations with our allies. We hope and we believe that at the end of the day, there will be a process of working with the other countries that are our friends."

European Commission trade officials have floated a possible list of American goods that might be targeted if Trump makes good on his threat of tariffs. The items include Harley Davidson motorcycles (made in Wisconsin), bourbon (made in Kentucky), orange juice, peanut butter and cranberries.

Resistance to these tariffs is strong. As the controversy unfolded, Gary Cohn, the head of Trump's National Economic Council, announced he would step down in a few weeks.
