During the Hillary Clinton email scandal, many liberals expressed their frustration with FBI Director James Comey's handling of the investigation, calling for him to resign or be fired.

Now that President Donald Trump has actually fired Comey, however, many of those liberals quickly have changed their tune.

Instead of criticizing Comey, Democrats like Sen. Elizabeth Warren, Sen. Patrick Leahy and Sen. Tim Kaine are now calling Trump un-American and authoritarian for firing the FBI director.

Another liberal who's had an about-face on Comey's firing is one of Trump's old sparring partners, Rosie O'Donnell.

In the days since Comey was fired, O'Donnell has gone on an anti-Trump tirade and railed against Comey's firing.

Trump pointed out in a tweet on Thursday that O'Donnell actually wanted to "FIRE COMEY" less than five months ago.

O'Donnell fired back on Thursday evening, calling Trump a "sadistic man" who is "very ill and needs help."
