The interview wasn’t pointedly anti-Trump, though Trump’s response suggests he felt it was.

Notably, Trump’s tweets mentioned Shep Smith, the former Fox News anchor whom the president had often targeted. Smith left the network in October.

Trump also lashed out at CNN and MSNBC as “fake news,” and called MSNBC by the nickname Fox News personality Sean Hannity uses: “MSDNC.”
