#Trump100Days US President Donald Trump celebrated the 100th day of his second term in office with a campaign-style speech, proclaiming his achievements and targeting political enemies.

Welcoming what he called a "revolution of common sense," he told a crowd of supporters in Michigan that he is using his presidency to deliver "deep changes."

The Republican mocked his Democratic predecessor Joe Biden and leveled new criticism at the head of the U.S. Federal Reserve, while dismissing polls that show his own popularity is declining.
