U.S. citizen arrested in attempted firebombing of U.S. Embassy office in Tel Aviv

• Social media posts from an account believed to be used by him also revealed threats to assassinate President Trump, the DOJ said.

Driving the news: Neumayer was taken into custody Sunday by FBI agents at John F. Kennedy International Airport in New York after being deported from Israel, federal prosecutors said.

• Prosecutors allege that Neumayer arrived in Israel last month. On May 19, he traveled to the U.S. Embassy office, wearing a backpack, and spat at a guard without provocation.
• The guard attempted to detain him, but Neumayer broke free, per the DOJ. He left behind his backpack, which was carrying three Molotov cocktails, according to a complaint filed in the Eastern District of New York.
• A review of his social media revealed he had allegedly posted earlier in the day, "join me as I burn down the embassy in Tel Aviv. Death to America, death to Americans, and f**k the west."
• Law enforcement tracked him to his hotel, where he was arrested. Neumayer was returned to the U.S. on Sunday.

What they're saying: "This defendant is charged with planning a devastating attack targeting our embassy in Israel, threatening death to Americans, and President Trump's life," said Attorney General Pamela Bondi in a statement, vowing to prosecute him to the "fullest extent of the law."

• Neumeyer was charged with attempting to destroy, by means of fire or explosive, the embassy building. If convicted, per the DOJ, Neumeyer faces a minimum of five years in prison and a maximum of 20 years.
• FBI director Kash Patel characterized his behavior as "despicable and violent."
