US President Donald Trump on Sunday said the FBI was so caught up in the Russia probe that it failed to heed signs, which could have prevented the Parkland school shooting.

His comments came as he faces criticism from survivors of the attack over his ties to the powerful National Rifle Association, and after several thousand rallied in Florida to demand urgent action on gun control.

"Very sad that the FBI missed all of the many signals sent out by the Florida school shooter. This is not acceptable," he wrote on Twitter. "They are spending too much time trying to prove Russian collusion with the Trump campaign - there is no collusion. Get back to the basics and make us all proud!"
