Ive been wondering about this connection with Susan Rice. We know that Rice was the one who was unmasking people in the Trump organization and then administration. She also adamantly denies doing it. However, it is entirely possible that someone who has her utmost trust, such as her administrative assistant Eric Ciaramella who has authority to sign her name to documents, COULD have been doing it in her name, someone such as CIA officer and analyst Ciaramella. That kind of thing has his pattern of activity written all over it.
After the inauguration of President Trump, we know that he was assigned to White House duty by the CIA. We also know now that after about four or five months there, he left his new post in the White House, the leaking of presidential phone calls suddenly stopped. That could possibly have been due to the change in where the transcripts of those particular phone calls were stored, moving them to a more secure, limited distribution-list, higher security server, but the timing is suspicious in that it coincides with his reassignment back to the CIA headquarters. He also could be the author of the infamous NYT article penned by the White House insider resistance bragging about their efforts to block Trumps agenda. It all circumstantially fits.
