Cole Tomas Allen, 31, wearing an orange shirt and trousers, was handcuffed and shackled as he was brought into the courtroom in Washington, D.C., federal court. His handcuffs were attached to a chain around his waist, which clanked as he was led to the defense table.

Speaking on behalf of Allen, federal public defender Tezira Abe said her client “pleads not guilty to all four counts as charged,” including attempting to assassinate the president of the United States, in connection with the April 25 incident at the Washington Hilton hotel.

Assistant U.S. Attorney Charles Jones advised the court that they plan to start producing their first tranche of discovery to the defense by the end of the week.

Officials said Allen, a California teacher and engineer, was armed with multiple guns, as well as knives, when he sprinted through a security checkpoint near the event where Trump and other White House officials had gathered with journalists.

He was arrested after an exchange of gunfire with a U.S. Secret Service officer who fired at him multiple times, a criminal complaint said. Allen was not shot during the exchange. The officer, who was wearing a ballistic vest, was shot once in the chest, treated at a hospital and released.

Trump and top members of his Cabinet and Congress were quickly evacuated from the room as others ducked under tables.

Allen was initially charged with attempting to assassinate the president, transportation of a firearm and ammunition through interstate commerce with intent to commit a felony, and discharge of a firearm during a crime of violence. On Tuesday, a federal grand jury indicted him on a new charge in the shooting of a Secret Service agent.

Moments before the attack, Allen had sent his family members a note apologizing and criticizing Trump without mentioning the president by name, according to a transcript of some of his writings provided to NBC News by a senior administration official. Allen also wrote that “administration officials (not including Mr. Patel)” were “targets.”

He also appeared to have taken a selfie in his hotel room. Prosecutors said Allen, who was dressed in a black button-down shirt and black pants, was “wearing a small leather bag consistent in appearance with the ammunition-filled bag later recovered from his person,” as well as a shoulder holster, a sheathed knife, pliers and wire cutters.

Officials have said they believe Allen had traveled by train from California to Washington, D.C., before checking into the hotel.

Allen’s sister, Avriana Allen, told law enforcement that her brother would make radical comments and constantly referenced a plan to fix the world, but said their parents were unaware that he had firearms in the home and that he would regularly train at shooting ranges.

Records show that he had purchased a Maverick 12-gauge shotgun in August 2025 and an Armscor Precision .38 semiautomatic pistol in October 2023.

After his arrest, Allen told the FBI that he did not expect to survive the incident, according to Assistant U.S. Attorney Jocelyn Ballantine. He was briefly placed on suicide watch at the Washington, D.C., jail, where he’s being held.

Allen is expected to appear in court for a June 29 hearing.

At Monday’s arraignment, his legal team said they plan on asking for the “entire office” of the U.S. attorney for the District of Columbia to be recused because of U.S. Attorney Jeanine Pirro’s apparent involvement in the case in a “supervisory role.” Federal public defender Eugene Ohm said some of the evidence they receive from the government will further inform that decision.

A cluster of earthquakes have struck near the U.S.-Mexico border, including ones with a 4.5 and 4.7 magnitude, according to the United States Geological Survey.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.

Seventeen U.S. cruise passengers are expected to return stateside early Monday, after weeks aboard the M/V Hondius, the cruise ship at the center of a deadly hantavirus outbreak.

The Americans are disembarking the cruise in the Canary Islands and boarding a medical repatriation flight, arranged by the U.S. government, bound for Nebraska. After landing at the Offutt Air Force Base near Omaha, they’ll head to the National Quarantine Unit at the University of Nebraska Medical Center (UNMC) for an initial evaluation, according to the Centers for Disease Control and Prevention.

“For the passengers getting off the ship, I’d say, ‘Welcome to Nebraska.’ You are coming to the premier facility in the United States, if not the world, to take care of you,” says Dr. Ali Khan, dean of the College of Public Health at UNMC.

The 17 U.S. passengers are among the total of nearly 150 people who were on the ship from 23 different countries. They’ve endured in the midst of a hantavirus outbreak which has caused at least eight cases, including three deaths, according to the World Health Organization.

The returning Americans had been isolating in their cruise cabins. They will now be monitored for several more weeks, U.S. health officials said in a media call on Saturday.

The passengers are arriving at America’s only federally funded quarantine unit, which also received cruise passengers from a different outbreak — the Diamond Princess Cruise, in early 2020 — which was one of the first known superspreading events of the COVID-19 pandemic.

Unlike COVID, which was a novel pathogenic strain when it emerged, scientists have been studying hantaviruses — and specifically the Andes variant which caused this outbreak — for decades. “We do know that you can get small clusters of disease, but in 30 years we’ve never seen any large outbreaks,” says Khan, “so this is unlikely to become a pandemic.”

This strain of hantavirus can be deadly, but it isn’t very contagious between people. It tends to take prolonged, close contact with someone who’s showing symptoms.

So far, all of the U.S. passengers are well. But symptoms can take up to 42 days after exposure to show up, according to the CDC.

“It’s appropriate to be cautious,” Khan says, “To monitor these people for 42 days [to make sure] they don’t get sick. And if they do get sick during those 42 days, to make sure to put them into isolation.”

Health officials said the U.S. passengers would not be officially quarantined. Instead, they suggested that after an initial assessment in Nebraska, some could continue monitoring at home, with daily check-ins from their health departments.

Seven U.S. passengers who had left the cruise ship earlier are being monitored in several states, including Texas, California, Georgia and Virginia.

Public health experts have been raising alarms over what they consider to be a muted public response by the U.S. government to this outbreak.

Lawrence Gostin, professor of global health law at Georgetown University, says the U.S. response has been fragmented, disjointed, and delayed for weeks, but it’s finally coming together. “The CDC was missing in action for quite a long time,” he says. “Better late than never — but it is very late.”

In response to a request for comment from NPR, Emily Hilliard, a spokesperson for the Department of Health and Human Services: “These claims are completely inaccurate. The U.S. government is conducting a coordinated, interagency response led by the Department of State. HHS, through ASPR [Administration for Strategic Preparedness and Response] and CDC, is supporting efforts to protect the health and safety of U.S. citizens, including repatriation, medical evaluation, and public health guidance.”

She further described CDC’s response activities, including setting up its Emergency Operations Center, deploying teams to the Canary Islands and Nebraska, and notifying state health departments of returning U.S. travelers.

Many of these activities have come recently, and Gostin agrees that the U.S. government is now taking active measures to ensure that the passengers, their families, and the communities they’re returning to are safe.

But health officials got lucky this time: the Andes virus is not very contagious, and health officials say this outbreak will likely be contained. The way the U.S. has handled this episode shows glaring gaps in its pandemic preparedness, Gostin says: “If this was a highly transmissible virus, you could imagine what chaos we would be facing now.”

Gostin says more investment is needed in infectious disease prevention, containment and control.
