An anonymous article in the New York Times, attributed to a "senior official in the Trump administration", claimed that the President "complained for weeks about senior staff members letting him get boxed into further confrontation with Russian Federation".
British authorities and the global chemical weapons watchdog say the victims were exposed to Novichok, a type of military-grade nerve agent developed by the Soviet Union during the Cold War.
London blamed the Russian state for the attack, but Moscow strongly denied any involvement.
The poisoning has sparked a Cold War-style diplomatic crisis between Russian Federation and the West, including the expulsion of hundreds of diplomats from both sides.
The suspects are Russians, identified as Alexander Petrov and Ruslan Boshirov, though British authorities say the names are probably aliases. Scotland Yard now wants help to find the two men, who flew from the U.K.to Moscow on the same day the Skripals fell ill.
He appealed to the public "to come forward and tell us who they are". It was not their first trip to Britain.
Six months after the chemical weapons attack rocked the quiet cathedral city, police released new details about what Basu called "one of the most complex investigations" the force had ever seen.
"We do not believe Dawn and Charlie were deliberately targeted, but became victims as a result of the recklessness in which such a toxic nerve agent was disposed of", said Neil Basu, head of Counter Terrorism Policing.
Detectives believe the front door of Mr Skripal's Salisbury home was contaminated with the military-grade substance on Sunday March 4.
Basu noted that traces of Novichok contamination were found in the London hotel room where the two men had stayed.
The two men alleged to have been behind the March nerve agent poisoning - Alexander Petrov and Ruslan Boshirov - have been identified by the United Kingdom as members of the GRU, Russia's military intelligence service.
They are also charged with use and possession of Novichok, contrary to the Chemical Weapons Act.
A European arrest warrant has been issued for the two Russians, who were named as Alexander Petrov and Ruslan Boshirov, the prosecutors said.
He said: 'I spoke to doctors and nurses and they say it doesn't look good - he doesn't have long left to live I fear.
And as she promised to get co-ordinated global action to root out the GRU from infiltrating Western nations, a senior Tory warned that Mr Putin's regime was now being run as a "gangster operation" sending "hoods and murderers to kill our citizens".
Rowley had told police that he found a box he thought contained perfume in a charity bin, Basu said.
Over the course of two days, the men traveled from London to Salisbury, England, twice - once to perform reconnaissance around the Skripals' home, and again to put lethal poison on their front door, police say.
"The Russian side has numerous questions for London".
The US ambassador to London, Woody Johnson, and the Australian government have also offered their support for Britain's stance against Russian Federation.
