After drops in the stock market, outcry from the Big Three automakers in the U.S. and a conversation with Mexico's president, President Trump again reversed himself and is delaying tariffs against Mexico and Canada.

It was just the latest chapter in a chaotic rollout of one of Trump's favorite economic tools, one that economists broadly say will lead to higher prices. Many tariffs on lots of goods are still in place, and the delay on the rest only extends until April 2, leaving companies and consumers unsure of what to expect, sometimes hour to hour.

"It may be a little bit of an adjustment period," Trump said in his address to a joint session of Congress Tuesday, acknowledging economic repercussions that could result from tariffs, and he asked Americans, farmers in particular, to "bear with me."

Here's a look at just some of Trump's back-and-forth on tariffs since taking office, leading up to this week:

Feb. 4: 10% tariffs are, in fact, put in place against China with China issuing retaliatory tariffs. The Postal Service puts a ban on packages from Hong Kong and China.

Feb. 5: The Postal Service reverses course and lifts the ban it put in place on Chinese packages because of the potential to create massive disruptions for online retailers and U.S. shoppers.

Feb. 10: Trump says he 25% tariffs on steel imports from all countries, and he raises aluminum tariffs from 10% to 25%.

Feb. 13: Trump signs a memorandum that sets the stage for "" to go into effect across the board on April 2.
