The new additions to the social media network also earned some groaning from former Obama speechwriters Jon Favreau and Jon Lovett, who complained that the president's senior adviser and communications director, Dan Pfeiffer, hadn't allowed them onto the social media network during their time at the White House.

Whithorne later acknowledged the movement in a tweet, joking that lower press — the tight West Wing quarters occupied by the communications staff — "just entered [the] 21st century."

"No we just need some windows," he added.
