Kamala Harris claims she 'didn't hear' supporter who called Trump 'mentally retarded.' It does not go over well.

During a campaign stop in Londonderry, New Hampshire, on Friday, a supporter of Democratic presidential contender Sen. Kamala Harris (D-Calif.) called President Donald Trump "mentally retarded."

"What are you going to do in the next one year to diminish the mentally retarded actions of this guy?" the supporter asked Harris, referring to Trump.

"Well said. Well said," Harris responded with a laugh. "Well, I plan to win this election, I'll tell you that."

After backlash, Harris responded to the incident on Saturday, claiming that she "didn't hear" the words her supporter used despite laughing at what he said.

"When my staff played the video from my town hall yesterday, it was upsetting. I didn't hear the words the man used in that moment, but if I had I would've stopped and corrected him," Harris said. "I'm sorry. That word and others like it aren't acceptable. Ever."

Later, after being confronted by an NBC reporter at the New Hampshire Democratic Party State Convention, Harris doubled down.

"Let me just be really clear. I would never condone that kind of language being spoken by anybody about anybody. It is offensive," she said, according to Politico. "I would never condone anyone using that word in any way shape or form, even against the guy I am running against. Period."

What was the reaction?

Considering Harris laughed at the supporter's choice of words, people did not believe Harris' claim that she "didn't hear" what the man said.

"I'm glad you know you're in the wrong, but what exactly were you laughing at? He asked what are you going to do about this President? If we believe your story you laugh at basic questions, or you r lying. Not a good look," one person responded on social media.

"I think it's clear that you heard him and supported his use of those words. If you get the nomination I will be voting third party," another person said.

"This is the, what, 7th or 8th time that Harris has claimed impaired hearing to excuse herself from accountability in the campaign?" another person responded.

"You told him 'that's a great way to put it' but, okayyyyyy," another critic said.

"Those hurt by these words hear them clearly whenever they are used, like hateful racial slurs, they ring clear to those that suffer from their violent history. If you didn't hear what the man yelled out, what exactly were you laughing at when you replied 'well said'?" another person responded.
