He brought a pump-action shotgun, a .38-caliber handgun and three knives, officials said.</p><p class="css-ac37hb evys1bk0">Mr. Allen appeared briefly in federal court in Washington on Monday, wearing a neon blue jumpsuit. He did not enter a plea and is likely to remain behind bars indefinitely. A magistrate judge scheduled a detention hearing in the case for Thursday.</p><p class="css-ac37hb evys1bk0">Mr. Allen’s sudden sprint past a security checkpoint while carrying deadly weapons created a harrowing security incident for the more than 2,000 people attending the White House Correspondents’ Association dinner at the Washington Hilton. The episode renewed questions about political violence and the security measures necessary to protect a president who has been the target of multiple assassination attempts.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-1"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-1"><div class="css-53u6y8"><p class="css-ac37hb evys1bk0">In a federal affidavit unsealed on Monday, an F.B.I. agent said that around 8:40 p.m. on Saturday, Mr. Allen approached a security checkpoint inside the hotel, where Mr. Trump, Vice President JD Vance and members of the cabinet were attending the dinner in the ballroom one floor below.</p><p class="css-ac37hb evys1bk0">Mr. Allen ran through a magnetometer holding a 12-gauge pump-action shotgun, and Secret Service agents “heard a loud gunshot,” the affidavit stated. One agent was shot in the chest but was wearing a bulletproof vest, according to the affidavit, which did not say that it was Mr. Allen who shot the agent.</p><div class="css-kbghgg"><div class="css-121kum4"><div class="css-171d1bw"></div><div class="css-asuuk5"><noscript><div class="css-7axq9l" data-testid="optimistic-truncator-noscript"><svg aria-hidden="true" class="css-1b5b8u1" data-tpl="i" height="24" viewbox="0 0 24 24" width="24"><path clip-rule="evenodd" d="M2.5 12a9.5 9.5 0 1 1 19 0 9.5 9.5 0 0 1-19 0Zm8.5 1.75v-7.5h2v7.5h-2Zm0 2v2h2v-2h-2Z" fill="currentColor" fill-rule="evenodd"></path></svg><div class="css-6yo1no" data-testid="optimistic-truncator-noscript-message"><p class="css-3kpklk" data-tpl="t">We are having trouble retrieving the article content.</p><p class="css-3kpklk" data-tpl="t">Please enable JavaScript in your browser settings.</p></div></div></noscript><div class="css-1dv1kvn" id="optimistic-truncator-a11y" tabindex="-1"><hr/><p>Thank you for your patience while we verify access.
