Welcome to the new Washington of Donald Trump and Elon Musk.

The president-elect and the world’s richest man combined Wednesday to smash a short-term spending compromise orchestrated by Republican House Speaker Mike Johnson to keep the government open until early in Trump’s new term.

The stop-gap measure is packed with nearly $100 billion in aid for Americans hit by multiple national disasters, economic aid for farmers, a federal commitment to rebuild Baltimore’s Francis Scott Key Bridge and a criminalization of revenge porn.

But the Trump-Musk blocking maneuver plunged the capital into one of its classic year-end crises, pitched Johnson’s hopes of keeping his job into extreme doubt and offered a preview of the chaos that may churn in Trump’s second term.

A sense of turmoil was exacerbated by the 10th straight day of losses on the Dow Jones Industrial Average, matching a mark set in the Ford administration. The selloffs underlined a volatile national moment and some of the economic challenges Trump may face after the Federal Reserve warned that inflation will tick up next year.
