Trump’s top economic advisor just quit

Trump's top economic advisor, Gary Cohn, has quit. He's the latest in a series of high-profile resignations.

What it means: It's been reported that Cohn has quit because he doesn't like Trump's decision to impose heavy charges (called tariffs What's this? ) on steel and aluminium imports. To sum up: the idea behind the tariffs is to protect US steel and aluminium manufacturers. If it's more expensive to import, people will be more likely to buy American, which helps the industry out and provides jobs. It's known as protectionism What's this? . The thing is, when Trump announced that plan people started getting scared there'd be a full on 'trade war' with other countries, including the EU.

It's not clear yet who Trump'll appoint in Cohn's place. Cohn – apparently a Democrat – had been a 'moderating' voice in Trump's team, although he did support other controversial Trump policies like his tax plan. He's the second person to resign in, like, two weeks. Trump's communications advisor Hope Hicks left last week.
