“I beg you, please bring him home for Christmas.”
She tagged the message @RealDonald Trump and added the hashtag #PardonAssange

Ms Morris has said he has been confined exclusively to his cell for over a week because of a coronavirus outbreak on his block at London’s Belmarsh Prison.
Mr Assange, the founder of WikiLeaks, attended four weeks of an extradition hearing at the Central Criminal Court in London in September and October. The judge overseeing the case said she would deliver her decision on 4 January.
US prosecutors have indicted Mr Assange on 17 espionage charges and one charge of computer misuse over WikiLeaks’ publication of secret American military documents a decade ago. The charges carry a maximum sentence of 175 years in prison.
Mr Assange’s defence team argues that he is a journalist and entitled to First Amendment protections for publishing leaked documents that exposed US military wrongdoing in Iraq and Afghanistan. They have also said the conditions he would face in a US prison would breach his human rights.
Mr Assange jumped bail in 2012 and sought asylum at the Ecuadorian Embassy in London, which ended up becoming his home for seven years before he was evicted and subsequently arrested. He has been in a London prison since April 2019.
Last week, Mr Morris said: is partner Stella Morris, the mother of their two young children, said: “Keeping Julian in the UK's harshest prison, exposed to a deadly virus and away from his family is not only cruel, it offends British values and democracy itself.
