1️⃣ US President *Donald Trump is set to begin his first full day in office,* riding a wave of *executive orders signed just hours after his inauguration* on everything from immigration to the environment and culture wars. 🇺🇸 *After the pomp of his inauguration ceremony,* the president's Tuesday is expected to start with a more solemn event: a prayer service at the National Cathedral. *It was unclear if or when more executive orders would come from Trump,* as the country and world digest the blizzard of actions he took Monday -- including initiating *withdrawals from the Paris climate accord and World Health Organization.* *Signed in front of roaring supporters* at an arena and then later in the Oval Office, the *long list of policy changes offered a symbol of Trump's increased preparedness* versus eight years prior, when he entered the White House with no governing experience.
