Donald Trump criticized Mitt Romney and called him a "total loser that only a mother could love" in response to excerpts from a new biography on Romney by McKay Coppins titled "Romney: A Reckoning. " In the book, Romney is quoted as being critical of Trump's leadership and saying Trump represents a "failure of character". Romney also said Republicans cheered when Trump said to put aside the Constitution. Trump took credit for Romney deciding not to run for reelection to the Senate, saying he forced Romney out. However, Romney announced his retirement last month after winning the election in 2018. Coppins' new biography provides insights into Romney's relationship with Trump and criticism of the former president's impact on the Republican party and constitution.
