First lady Melania Trump arrives for President Trump’s address before Congress.

President Donald Trump is scheduled on Tuesday to address a joint session of Congress, as his second administration moves to recast the federal government, implement “America First” policies and redefine U.S. support for Ukraine.

The speech comes after markets tumbled following Trump’s steep tariffs on key U.S. trading partners. Meanwhile, his administration could sign a mineral deal with Ukraine as soon as today after a tumultuous Oval Office meeting last week between Trump, Vice President JD Vance and Volodymyr Zelenskyy.

Trump will defend the steep tariffs on Canada, China and Mexico after markets roiled and the key U.S. trading partners vowed retaliation.

“Whatever they tariff us, we tariff them. Whatever they tax us, we tax them. If they do non-monetary tariffs to keep us out of their market, then we do non-monetary barriers to keep them out of our market. We will take in trillions of dollars and create jobs like we have never seen before,” Trump will say, according to excerpts of his speech released by the White House

Four sitting members of the U.S. Supreme Court are in attendance for Trump’s address tonight: Chief Justice John Roberts, Justice Elena Kagan, Justice Brett Kavanaugh, and Justice Amy Coney Barrett. Retired Justice Anthony Kennedy is also present.

This is a slightly smaller showing from the court compared with recent presidential addresses to Congress as six attended in 2024, five attended in 2023, and five attended in 2022.

During Trump’s first term, however, only four justices ever attended each of Trump’s addresses before Congress.

Trump will shake hands with and speak before members of the Supreme Court at a time when his administration is seeking its emergency intervention in two pending cases related to his executive actions — one involving his power to fire any employee of the executive branch for any reason, and the other involving his power to freeze foreign aid that Congress has authorized for specific programs.

To date, the Supreme Court has not yet weighed in in any meaningful way on Trump’s asserted presidential powers during his second term.
