President Biden decided to cut short his weekend vacation and return to the White House on Saturday for consultations ahead of a possible Iranian attack against Israel, the White House said.

Why it matters: Biden's decision signals that the White House thinks the Iranian attack could be imminent and take place within hours, according to sources with knowledge of the situation.

President Biden said Friday he expects Iran to launch an attack against Israel "sooner than later" and stressed his message to Tehran is: "Don't".

Why it matters: The Biden administration is concerned an Iranian attack and an Israeli retaliation could lead to another serious escalation in the region.

Iran sent a message to the Biden administration through several Arab countries earlier this week: if the U.S. gets involved in the fighting between Israel and Iran, U.S. forces in the region will be attacked, three U.S. officials told Axios.

Why it matters: The U.S. and Israel are preparing for Iran to retaliate against Israel for an airstrike that killed a top Iranian general in Damascus last week.

The FBI is growing increasingly concerned about a potential attack in the U.S. similar to last month's Russia concert hall shooting, bureau director Christopher Wray said Thursday.

The big picture: "As I look back over my career in law enforcement, I would be hard-pressed to think of a time where so many threats to our public safety and national security were so elevated all at once," Wray told lawmakers as he urged Congress to reauthorize Section 702 of the Foreign Intelligence Surveillance Act (FISA).
