Suspect charged with attempted assassination of Trump at Washington dinner

Attempting to assassinate the president carries a potential life sentence.

The other charges - transportation of a firearm between states to commit a felony and discharging a firearm in a crime of violence - both have maximum sentences of 10 years.

At Monday's news conference, Pirro said the suspect's intent, based on writing he sent to his family before the attack, was to bring down as many high-ranking cabinet members as he could.

Prosecutors requested that Allen remain detained, arguing that the assassination attempt charge could be considered terrorism. Pirro said more charges could be filed.

As US investigators look into the third alleged assassination attempt against Trump, security officials are reviewing how the situation was handled, and how to beef up protection of the president.

Many have questioned whether the security perimeter at the Washington Hilton was strong enough, why attendees were never asked to show identification at the event, and why the president, vice-president and others in the line of succession were all gathered in one place.

In Monday's news conference, Blanche maintained that "law enforcement did not fail" in its job to protect the event.

He noted that one thing should be "clear" - the gunman was one floor away, "with hundreds of federal agents between him and the President of the United States".

A senior White House official told the BBC that Trump was "standing by" the leadership of the Secret Service, an arm of the Department of Homeland Security (DHS) that protects high-level government officials.

White House Chief of Staff Susie Wiles will convene a meeting this week to "discuss protocol and practices for major events", the official also said.

At a news briefing on Monday, White House Press Secretary Karoline Leavitt said Trump "believes the protocols worked" for security on Saturday and blamed rising political violence on the rhetoric of Democrats.

Trump has offered assurances that King Charles III will "be very safe" during his four-day state visit to the US, which began on Monday at the White House.

The president's security detail must meanwhile prepare for a rescheduling of the White House correspondents' dinner.

FBI Director Kash Patel told Fox News on Monday that "we're going to be so ready" for Trump to attend the event in the next 30 days and that "the security posture, I imagine, is going to be completely different".

No new date has yet been set for a second try at the annual dinner.

Preparations for the event typically take months.

The Washington Hilton, where John Hinckley Jr attempted to assassinate then-President Ronald Reagan 45 years ago, said it followed security instructions from the Secret Service.

"The hotel was operating under stringent security protocols for the property as directed by the US Secret Service, which led security for the event," it said in a statement, according to Reuters, adding that it had worked with local police and other security teams.
