Donald Trump's senior adviser Kellyanne Conway said in a CNN interview on Sunday many Trump supporters would feel "betrayed" if he named Mitt Romney the new Secretary of State.
I'm all for party unity, but I'm not sure we have to pay for that with secretary of state position.
But Conway implied picking Romney would counteract what many Trump supporters stood for.
Romney was an outspoken critic of Trump, calling him "a phony, a fraud" and said his policies could create "trickle-down racism." Trump has said Romney "choked" in his 2012 presidential campaign.
Conway tweeted this on Thursday, illustrating her point.
In a separate interview, she said Romney had gone "out of his way to hurt Donald Trump."
Republican CNN commentator Ana Navarro called Conway's interview "astounding."
Meanwhile, Newt Gingrich said "we" would be "disappointed" by a Romney pick.
