Marjorie Taylor Greene, a loyal supporter-turned-critic of US president Donald Trump, has said she is resigning from US congress in January.

In a video posted online, the Georgia representative said she did not want her congressional district “to have to endure a hurtful and hateful primary against me by the president we all fought for”.
