CBS News reports (scroll down):

CBS News has confirmed from two sources that three leakers of classified information at the White House have been identified and are expected to be fired.

Officials within the Trump White House believe leaks of Mr. Trump's conversation with Russian Foreign Minister Sergey Lavrov are a "deliberate attempt" by officials who are holdovers from President Obama's administration and are trying to damage the Trump presidency.

I'm guessing maybe translators - civil servants of some sort. They aren't easy to fire but could be transferred to the GSA where careers go to die.
