President Trump does not yet plan to comment on a Minnesota mosque bombing because the White House isn't sure that initial reports of who is responsible are true, national security aide Sebastian Gorka said Tuesday.

Minnesota Gov. Mark Dayton called the explosion at a mosque in Bloomington over the weekend "an act of terrorism."

Gorka said the White House would wait until the FBI's investigation was finalized to comment on the incident.

"There's a great rule: all initial reports are false. You have to check them, you have to find out who the perpetrators are," Gorka said. "We've had a series of crimes committed, alleged hate crimes, by right-wing individuals in the last six months that turned out to actually have been propagated by the Left."

When asked why Trump was quick to comment on other attacks, Gorka said it was "unequivocally clear" those incidents were terrorism.

"When someone shouts ‘Allahu Akbar' as they are stabbing a police officer, it's pretty clear it's not a case of a mafia robbing the bank," he responded. "When people fake hate crimes in the last six months with some regularity, it's wise to find out what exactly is going on before you make statements, when they could turn out to be not who you are expecting."
