Donald Trump's wife Melania has said "violence is never the answer and will never be justified" in her US First Lady farewell speech. In the speech, shared on Twitter on Monday, the US First Lady has spoken about violence after her husband's supporters rioted at the US Capitol building on January 6. Five people died including Police officer Brian Sicknick who was hit over the head with a fire extinguisher and US Air Force veteran Ashli Babbit, who was shot dead by police. Melania, 50, who has been married to the 74-year-old since 2005, made the speech ahead of Joe Biden's inauguration on Wednesday.

She said: "My fellow Americans, it has been the greatest honour of my life to serve as first lady of the United States. I have been inspired by incredible Americans across our country, who lift up our communities through their kindness and courage, goodness and grace. The past four years have been unforgettable as Donald and I conclude our time in the White House, I think of all of the people I have taken home in my heart and their incredible stories of love, patriotism and determination."

“As I say farewell to my role as First Lady, it is my sincere hope that every American will do their part to teach their children what it means to be best," she continued.

“I encourage parents to educate your children about the courageous and selfless heroes who worked and sacrificed to make this country the land of the free, and to lead by example and care for others in your community. The promise of this nation belongs to all of us. Do not lose sight of your integrity and values.”
