This incident marks another in a series of recent breaches that have tested White House security
The White House was briefly placed under heightened security on Tuesday afternoon after a mobile phone was reportedly thrown over the perimeter fence onto the North Lawn, Press Secretary Karoline Leavitt confirmed. The incident prompted the Secret Service to initiate a rapid protective lockdown, temporarily halting press activities.
At around midday, journalists assembled for a briefing scheduled with the Education Secretary were unexpectedly escorted indoors and prevented from approaching the lawn. Pennsylvania Avenue was also briefly closed to traffic as security teams assessed the potential threat.
Leavitt told media that an individual “threw their phone over the fence,” although the Secret Service has not corroborated whether the object was indeed a phone. The security alert was lifted shortly after, with lockdown measures ending by 11.56 am. By 12.20 pm, the press had reconvened inside the White House ahead of the president’s departure for an event in Pennsylvania.
This incident marks another in a series of recent breaches that have tested White House security. In March, a child briefed a breach when a young boy gained access to the perimeter and had to be returned to his parents by on-duty agents. Earlier cases, including a suspicious package in 2019 and a vehicle-based alert in 2018, also triggered rapid Secret Service responses.
The response this week underlines the vigilance with which the Secret Service treats even seemingly minor incidents, and adds fresh scrutiny to the agency’s protocols amid ongoing public concern. The White House itself has not yet released a formal statement on the event.
