U.S. Sen. John McCain rebukes President Donald Trump in a new memoir, accusing his fellow Republican of failing to uphold U.S. values by showering praise on international ¡°tyrants,¡± discrediting the media, ignoring human rights and demeaning refugees.

¡°Flattery secures his friendship, criticism his enmity,¡± wrote McCain in ¡°The Restless Wave,¡± which he co-authored with longtime aide Mark Salter.

¡°It is hard to know what to expect from President Trump, what¡¯s a pose, what¡¯s legitimate,¡± McCain said in the book that is due to be released on May 22. An advance copy was sent to Reuters by publisher Simon & Schuster.
