A complete timeline of Trump's years-long feud with Rosie O'Donnell

President Donald Trump on Thursday dug up a months-old tweet from Rosie O'Donnell to quip about FBI Director James Comey's recent firing.

O'Donnell's tweet, from December 20, 2016 read: "FIRE COMEY."

The tweet ostensibly referenced consternation among some Democrats who believed Comey's public comments about an investigation into Hillary Clinton's private email server cost her the White House.

"Rosie, we finally agree on something," Trump tweeted Thursday.

O'Donnell later told MSNBC that Trump's tweet was "a clear indication of his seriously declining mental health."

The tweet was just another wrinkle in the decade-long feud Trump and O'Donnell have had, which precedes Trump's career in politics and dates back to a disagreement about the handling of an incident involving one of Trump's beauty queens.

Here are the exchanges between O'Donnell and Trump over the years.
