Trump says 3M 'will have a big price to pay' over face masks

U.S. President Donald Trump slammed 3M Co in a tweet late on Thursday after earlier announcing he was invoking the Defense Production Act to get the company to produce face masks.

"We hit 3M hard today after seeing what they were doing with their Masks. 'P Act' all the way.' Big surprise to many in government as to what they were doing - will have a big price to pay!" Trump said on Twitter.
