Can Trump impose tariffs without Congress? It's complicated, according to experts.

President-elect Trump, who has said he thinks "tariff" is "the most beautiful word in the dictionary," has proposed a variety of taxes on goods imported from other countries. 

His aim is to deter American companies from relying on parts and goods from overseas, including from China, by making it more expensive for them to do so. 

He's also claimed that he doesn't need Congress' support to impose the tariffs he's floated. The reality is more complicated, according to economists and foreign trade experts.
