President Donald Trump's sweeping new tariffs on dozens of countries took effect on Thursday, fulfilling a long-promised pledge to reorder the global economy.This week, Trump is also expected to nominate a new head of the Bureau of Labor Statistics after abruptly firing the agency's top official last week after a weak jobs report.

President Donald Trump has removed former U.S. Rep. Billy Long as IRS commissioner less than two months after his confirmation.

Billy Long, who was sworn in just under two months ago, was already the sixth person to hold the job this year. He told NBC News he will be the next U.S. ambassador to Iceland.
