Melania Trump and her husband US President Donald Trump have walked the black carpet at the premier of her new documentary. Melania: Twenty Days to History, follows her in the run up to Trump's second inauguration, the first time a sitting first lady has featured in such a documentary. She also produced the film. Speaking at the premier, Mrs Trump said she wanted to "show other people what it takes to go from being a private citizen to first lady again." It is believed that Amazon paid around $40m (£29m) for the rights to the film, and another $35m (£25m) in marketing costs.
