Sebastian Gorka, deputy assistant to President Trump, warned the White House staff against leaking information saying the new White House chief of staff doesn't mess around.

"For those like myself that have nothing to hide, we're doing business as usual," Gorka said after being asked if the White House administration has tightened up during White House operations.

"For those who may have not been abiding by federal law when it comes to sensitive and classified information, I think they've got the message, and I think you will see things change very rapidly," Gorka added.

Gorka is a notable defender of the Trump administration in his frequent appearances with the media. On Saturday, he warned that "loose lips sink ships."

"This is John F. Kelly. This is a man you do not toy with," Gorka said on "Fox and Friends."
