Senator Kamala Harris, the first Indian-origin US Senator, has apologised for laughing and saying "well said" in response to a question from an Indian man who called President Donald Trump's actions "mentally retarded." The 54-year-old California Democrat and presidential candidate termed as "upsetting" the video, circulated on social media, of the Friday's incident at the New Hampshire town hall. She denied she had heard the offensive term.

"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. I'm sorry. That word and others like it aren't acceptable. Ever," Harris said in a tweet on Saturday. The questioner at the Londonderry town hall identified himself as being from Chennai, the same hometown as Harris' mother, and said he had spent "all this effort" to live the American dream and then Trump was elected, the CNN said in report.
