"He [Trump] is obviously very concerned about the disclosure of national security on any level. It undermines our country's national security," Spicer stated. "There is also been a big double standard when it comes to disclosures of classified information."
Spicer noted the Trump administration would go after persons who leak sensitive information and prosecute those responsible for the unauthorized disclosures.
On Saturday, Trump claimed that former President Barack Obama ordered surveillance of Trump Tower before the November 8 presidential election undertaken by six government agencies.
FBI Director James Comey disputed Trump’s allegation and asked the Justice Department to publicly denounce the claim.
The US House of Representatives Intelligence Committee Chairman Devin Nunes announced on Sunday that the panel would launch a probe into the allegations.
