President Trump plans to issue a memo Thursday calling for the U.S. Commerce Department to investigate whether steel imports hinder national security, as first reported by Bloomberg's Jennifer Jacobs. (Axios has confirmed Jacobs' reporting.)

Why it matters: By initiating investigations under the umbrella of "national security," Trump is creating a pretext for using extraordinary measures to crack down on steel dumping. This could complicate the U.S.-China relationship at a time when Trump is explicitly linking trade negotiations to China's behavior with North Korea, as China is the top culprit for dumping cheap steel into the American market.

Something else you should know: This memo is much, much, milder than some of the ideas that were initially kicked around inside the West Wing. An early concept pushed by Administration nationalists was to impose immediate supplemental 25% tariffs on a wide range of product categories they believed were being unfairly dumped into the United States such as industrial chemicals, household appliances, paper and tires.

Democratic and Republican lawmakers along with other leading figures paid tribute to Supreme Court Justice Ruth Bader Ginsburg, who died on Friday night at age 87.

What they're saying: “Our Nation has lost a jurist of historic stature," Chief Justice John Roberts said. "We at the Supreme Court have lost a cherished colleague. Today we mourn, but with confidence that future generations will remember Ruth Bader Ginsburg as we knew her — a tireless and resolute champion of justice.”

Justice Ruth Bader Ginsburg has died of metastatic pancreatic cancer at age 87, the Supreme Court announced Friday evening.

Why it matters: Ginsburg had suffered from serious health issues over the past few years. Her death sets up a fight over filling a Supreme Court seat with less than 50 days until the election.
