Information about terror attacks that occur in Europe is shared as a matter of course with American intelligence and law enforcement officials, who check their own files to see if suspects traveled to and from the US, and to offer any collaboration or support.
The president called on the DOJ to investigate and prosecute whoever is behind the leaks "to the fullest extent of the law".
Trump described as "deeply troubling" the leaks from the probe, which called into question intelligence-sharing between the key partners and cast a pall over his meeting with Prime Minister Theresa May in Brussels.
"I think it is important to remember that today's restrictions only seem to apply to law enforcement channels and not to intelligence sharing more broadly", said Shashank Joshi, an intelligence analyst and senior fellow at RUSI, referring to the police's decision to try and restrict information sharing.
In 2007, Al-Qaeda said the now-disbanded faction had joined its rranks, but this was denied by the LIFG, who said they had no ties with global organisations.
It was a message of defiance three days after Manchester-born Salman Abedi's attack on young fans attending a concert by USA pop star Ariana Grande.
In addition to those killed, 116 people have received medical treatment at Manchester hospitals for wounds from the blast. The victims ranged from an eight-year-old schoolgirl to parents who had come to pick up their children. Queen Elizabeth II visited Royal Manchester Children's Hospital, telling 14-year-old Evie Mills and her parents: "It's terrible".
After a series of police raids in and around Manchester, a total of eight people are in custody in connection with the suicide bombing.
Officials are particularly angry that photos detailing evidence about the bomb were published in the New York Times.
Mohammed Fadl, a spokesman for Libyan expatriates in Manchester, said Salman's family was well known in the community, especially his elder brother Ismail, but said Salman "was not socially involved in the community".
"I want to reassure people that the arrests that we have made are significant".
After May warned the United States to keep classified information "secure", Trump ordered his Justice Department to look into how sensitive information - including photos of the remains of the explosive device used in Monday's concert bombing - made their way into U.S. media.
But just hours after Ms Rudd complained, The New York Times newspaper again scooped British authorities and other media by publishing photographs from the scene of remnants of the bomb.
Abedi's father, Ramadan, told Reuters he spoke to his son days before the bombing and "everything was normal". "In any case, the links with Daesh are proven", he said, using a term for Islamic State.
Around the United Kingdom, many fell silent Thursday for a late-morning minute in tribute to the victims.
Shortly after, Queen Elizabeth arrived at Royal Manchester Children's Hospital to visit some of the injured.
With the official threat level raised to "critical", meaning a further attack could be imminent, troops have been deployed to free up police, and armed officers patrolled trains for the first time in Britain.
British soldiers are patrolling high-profile events such as football matches and concerts.
An EU Counter Terrorism official in Brussels echoed this assessment but also pointed to the UK's fears of increasing irrelevance in an era of Brexit and continued budget cuts to its own military and intelligence services.
In a statement issued by the White House, as Trump joined May at a meeting of North Atlantic Treaty Organisation allies, he said: "There is no relationship we cherish more than the special relationship between the United States and the United Kingdom".
