Trump's first day actions loom large as Davos begins

President Donald Trump has given everyone at Davos something to talk about with his actions on the first day of his second term. The World Economic Forum’s annual gabfest in the Swiss Alps gets into full swing on Tuesday. Ukraine's Volodymyr Zelenskyy and Ursula von der Leyen of the European Commission are among the headliners this year. Energy, trade, migration, U.S. territorial ambitions and the wars in Ukraine and the Middle East are likely to be discussed at Davos.
