As Donald Trump opened fire on Justin Amash, the Michigan representative who became the first Republican in Congress to call for his impeachment, Mitt Romney declined to join the fight.

Romney was scathing about the picture of the president that emerges from the Mueller report into Russian interference in the 2016 election, the redacted version of which he said he had spent two days reading in full. He said on Sunday its findings were “troubling, unfortunate and distressing”.
