What to know:

• Trump has not been shy about wanting to use federal law enforcement to target his perceived political enemies. Omar, a left-wing firebrand, has been a longtime target of Trump and Republicans in general. The agents who searched Omar’s home were Homeland Security investigators, indicating the investigation regards immigration issues. The Department of Justice on Monday was typically tight-lipped, giving few details about the case other than saying it was a criminal investigation. In a statement on X on Monday, Omar called the search an “attempt to target political enemies and weaponize federal law enforcement.”

Elon Musk quietly becomes biggest known donor in this year’s midterm contests

Elon Musk, the world’s only trillionaire, has doled out more than $276 million since July to try to save Republican majorities in Congress. The numbers, first reported by the New York Times ahead of this week’s federal filing deadline, were confirmed by Andrew Romeo, a spokesperson for Musk’s super PAC.  Read more.

What to know:

• The money includes $158 million given to the Senate Leadership Fund, the main super PAC supporting Republican Senate candidates, one of the largest known political donations in American history, according to the Times. It’s a dramatic turnaround since last May, when Musk said he intended to cut back on future political spending.
  
  

• Republicans have a gaping financial advantage over their Democratic counterparts — a disparity that has been a rare bright spot for a party that is bracing for major potential losses amid deep voter frustration over the president’s performance, stubbornly high prices and the unpopular war with Iran. They have been using the money to blanket the airwaves in the race’s final stretch.

Saudis probe how defense systems failed to stop deadly Houthi attack on Riyadh airport

Saudi Arabia has launched an investigation to determine how its air defenses failed to intercept a barrage of missiles and drones fired by Iran-backed Houthi rebels, including an attack on Riyadh airport that killed at least 13 people and wounded over 300, two regional officials said Monday. Read more.

Why this matters:

• The Saudis want the U.S. to become more directly involved in their fight against the Houthis. The U.S. has provided intelligence sharing, target identification and planning for a Saudi-led offensive, but has held off on carrying out strikes against the Houthis itself. President Donald Trump said Monday that he had spoken with Saudi Crown Prince Mohammed bin Salman, but didn’t offer any details about the call. Later on Monday, when asked if the U.S. will defend Saudi Arabia after Houthi attacks, Trump said, “You’ll find out soon.”
