President Trump hailed his return to office as the start of a "thrilling new era" that would bolster values such as democracy and freedom. Why it matters: While Trump's overtures reflected his intent to strike a warmer tone than in 2017 — when his inauguration speech decried "American carnage" — much of the content of his inaugural address retained the dark message of his first address.

President Trump said on Monday that a "tide of change" is sweeping the U.S., moments after he was sworn in as the 47th president of the United States.
