Runner up has to be from the Washington PostScreen Shot Ana Navarro (CNN: April 30, 2018)
Regular CNN commentator Ana Navarro joined the crowd attacking President Donald Trump for referring to MS-13 gang members as “animals,” apparently forgetting that she had used the same terminology to attack Trump during the 2016 campaign.
Just after the release of the infamous “Access Hollywood” tape, Navarro tweeted her disgust with then candidate Trump.
“Should Donald Trump drop out of the race? Yes,” she tweeted Oct. 10, 2016. “He should drop out of the human race. He is an animal. Apologies to animals.
.
”Jennifer Rubin, the self-described “conservative blogger” at the Washington Post, called President Trump’s comments “disgusting.”
But in August of 2017, Rubin also compared the president to an “animal” in an opinion piece that appeared in the Chicago Tribune.
“Only 24 hours after he read a serious speech off a teleprompter committing to send more young men and women to fight in Afghanistan, President Donald Trump reverted to form, delivering a rambling, rage-filled, 77-minute harangue that was alternately defensive, angry, accusatory and just plain weird. Like a trapped animal, he lashed out in every direction, trying unsuccessfully to draw blood.
It seems using a simile("like a trapped animal" ) is quite ok - it is metaphors that cross the line..
