President Trump is giving the strongest indications yet that he may try to fire Fed chair Jerome Powell — a legal and economic showdown with little modern precedent, Axios' Courtenay Brown reports.

• "If I want him out, he'll be out of there real fast, believe me," Trump told reporters today in the Oval Office.
• "Powell's termination cannot come fast enough!" Trump posted earlier in the day on Truth Social.

🏦 State of play: Trump is mad at Powell for not lowering interest rates.

• He said Powell should follow the lead of the European Central Bank, which cut rates again today because its outlook for the European economy is growing more pessimistic.
• Powell has said Trump's tariffs could cause inflation to spike.

👀 What we're watching: Federal law and Supreme Court precedent say presidents cannot fire the Fed chair over a policy disagreement.

• But the Trump administration is asking the Supreme Court to overturn that precedent and let the president fire the heads of independent agencies.
• The conservative court has generally sided with Trump in his push for more power to fire federal officials, but even a ruling in his favor in this case may not apply to the Fed.
• "I don't think that that decision will apply to the Fed, but I don't know. It's a situation that we're monitoring carefully," Powell said yesterday.

⚖️ Every lower court to consider the issue has ruled against Trump. Multiple judges have blocked his executive order on birthright citizenship from taking effect — and the high court said today it will leave the policy frozen while it considers the big-picture constitutional questions.

• Oral arguments are set for May 15.
