DAVOS, Switzerland (Reuters) - U.S. President Donald Trump touted the success of the U.S. economy in Davos on Tuesday, dismissing "perennial prophets of doom" on climate change to an audience that included Greta Thunberg.
With his impeachment trial set to begin in Washington, Trump largely shied away from environmental issues, which are top of the agenda at the gathering in a Swiss ski resort of business leaders for the annual meeting of the World Economic Forum.
