President Trump's principal deputy press secretary Hogan Gidley believes the White House's decision to designate Iran's Revolutionary guard as "foreign terrorist organization" is part of a plan to put pressure on the country to "change its behavior."

While speaking to "America's Newsroom" on Monday morning, Gidley defended the president's decision and said it illustrates Trump's ability to do what other administrations have threatened but not acted on.

"This is the first time the United States has recognized another government as a foreign terrorist organization," Gidley said. "A lot of other administrations have threatened it, but this President, again, came to the table and did it. It's an important move for the administration and for safety and security around the globe."

He went on to argue that there was no specific "tipping point" that catalyzed the decision, but that Iran's reputation as a "state sponsor of terrorism" has long been known.

The move is a part of an ongoing "maximum pressure campaign," Gidley said, that is intended to motivate Iran to "do something different than what they have been, which is wreaking havoc across the globe and sponsoring those who do."
