The U.S. President speaks to Congress after the dramatic start of the second semester

President Donald Trump will deliver his first joint speech to Congress in his second term, limiting a dramatic few months, unleashing a positive agenda to reshape U.S. trade and foreign policy.

The speech comes as Trump imposed a 25% tariff on Canada and Mexico, the largest trading partners of the United States, and an additional 10% tax on China.

All three countries say they plan to retaliate, causing U.S. stocks to fall on Tuesday.

Donald Trump’s remarks on Ukraine and Russia will be the most watched remarks of the night, following closely behind his moves to cut off military aid to Ukraine along with Ukrainian President Volodymyr Zelenskyy and the big Oval Office last week.

The shift in U.S. policy is huge. Joe Biden began his speech in his final speech as president a year ago, asking Congress and the United States to support Kiev, comparing his appeal to the 1941 call from Franklin Roosevelt, which in 1941 called for lawmakers to support democracy globally.

“We have to stand up and go to Putin,” Biden said. “History is looking. If the United States goes away, it will put Ukraine in danger. Europe is at risk. The free world will be at risk and make others willing to hurt us.”
