In a statement posted on the star athlete's Facebook page, he wrote: "On 1st January this year, Her Majesty the Queen made me a Knight of the Realm. On 27th January, President Donald Trump seems to have made me an alien. I am a British citizen who has lived in America for the past six years - working hard, contributing to society, paying my taxes and bringing up our four children in the place they now call home."
The athlete posted a statement on Facebook expressing his concern
He continued: "Now, me and many others like me are being told that we may not be welcome. It's deeply troubling that I will have to tell my children that Daddy might not be able to come home - to explain why the President has introduced a policy that comes from a place of ignorance and prejudice. I was welcomed into Britain from Somalia at eight years old and given the chance to succeed and realise my dreams. I have been proud to represent my country, win medals for the British people and receive the greatest honour of a knighthood. My story is an example of what can happen when you follow polices of compassion and understanding, not hate and isolation."
Mo moved to Britain from Somalia aged eight
The Somalia-born Olympian, who moved to Britain at the age of eight, also shared a link to the statement on Twitter, simply writing: "My response to Trump - thanks for all the support guys." Mo's supporters were quick to praise his statement, with one writing: "Good for you Mo. We've got your back," while another added: "We are all hugely proud of you. Well done for speaking truth to power."
