Trump calls Boeing a 'big, big disappointment'

President Donald Trump on Wednesday criticized Boeing as a "very disappointing company" because of the aerospace giant's recent problems, which he said had a knock-on effect for the US economy.

"This is one of the great companies of the world, let's say as of a year ago, and then all of a sudden things happen," Trump said in an interview on CNBC from the Davos economic forum in Switzerland.

This "had a tremendous impact. You know, when you talk about growth, it's so big that some people say it's more than a half a point of GDP. So Boeing -- big, a big disappointment to me," he said.
