What Is the Chief of Staff in a Normal White House?

The president's chief of staff is texting with members of Congress about conspiracy theories and Romanian YouTube links. Mika Brzezinski asks: Is that normal to be hearing from dozens of members of Congress, conspiracy theories? What do you make of this text by representative Ralph Norman about martial law? There are so many different ways to go here, but I'm just wondering what your thoughts in terms of covering the White House about the role of the chief of staff and what was going on here?"
