🔮 I'm frustrated that I got it in the middle of the night, but I'm much more concerned that it's filed on the public record." The assistant U.S. attorney in the hearing, John Borchert, struggled repeatedly as Faruqui asked him to explain the government's conduct, which the judge said was unlike any case he had ever seen in the history of D.C.'s district court. Faruqui ultimately granted the request from Flores' and Benavides' attorneys to strike the amended complaint from the docket and said he would continue Tuesday's hearing to determine whether prosecutors established probable cause in their initial complaint filed last week. "Why today on this one case have you changed the entire history of how you charge cases?" Faruqui asked of Borchert.
🔮 She could not immediately be reached for comment on Tuesday.
🔮 Unglesbee said he knew recipients of white powder letters 'took it serious and would have 'hazmat come in white suits' because 'anthrax is dangerous.'
🔮 The report lays out a series of warning behaviors and signs that are typical for those who might carry out targeted workplace violence, like a 22-year-old service member who "experienced multiple stressors, including chronic pain resulting from a motorcycle accident, the ailing health of a loved one, harassment from peers, and numerous reprimands and citations at work due to poor performance and tardiness," before carrying out an attack that killed two on base and injured a third person.
🔮 In a follow-up post resharing the letter, Trump wrote "They will all go to jail for a long period of time!!!"
🔮 We will continue to monitor developments closely as the facts become clear.

🔮 Nepal used encrypted apps to exploit minors through "rules," which were needed for the child to join the so-called network, and leaders would force minors "to engage in self-mutilation, online and in-person sexual acts, harm to animals, sexual exploitation of siblings and others, acts of violence, threats of violence, suicide, and murder," according to the news release.
🔮 "Van Rootselaar wanted to select a location that would lead to the largest number of victims.
🔮 Mullin says US 'knew' Iran would try to attack American assets in UK U.K police said Thursday they arrested another man in connection with the case. The United States knew Iran or its proxies were going to "try and do an attack, possibly on a United States asset in the [United Kingdom]," Secretary of Homeland Security Markwayne Mullin said Thursday of the arrest and release of five men near a Royal Air Force base used by the U.S. Mullin told Fox News the U.S. "had already been watching" the situation with British officials and the U.S. was "giving them a heads up." His comments come after U.K. Prime Minister Andy Burnham said Wednesday he believes Iran "played a part" in last weekend's incident at a Royal Air Force base in England that hosts U.S. warplanes involved in the conflict with Iran.
