Warren Buffett said trade should be balanced between countries and said Trump's widespread tariffs are not the right answer.

Warren Buffett has been silent about the Trump tariffs since they were announced. That could come to an end this weekend. Investors and economic onlookers will be paying even more attention than usual to the Oracle of Omaha's annual address to Berkshire Hathaway shareholders this Saturday.

Prior to the meeting, Warren Buffett remained mostly quiet on Trump’s controversial tariff policy, which escalated a trade war with China and provoked backlash from longtime trading partners.

National security adviser Mike Waltz is leaving his White House post, although soon after reports about his departure were published, President Trump announced he plans to nominate him to be ambassador to the United Nations.

CBS News also reported that Waltz's former deputy, Alex Wong, fired in the shakeup, remains at the National Security Council.

President Donald Trump said Thursday that he would nominate outgoing national security adviser Mike Waltz to be the U.S. ambassador to the United Nations. Waltz, a former congressman from Florida, has been on shaky ground with Trump since March after he inadvertently added a journalist to a private chat on the messaging app Signal with other top national security officials to discuss military strikes in Yemen.
