China News Service, June 4th, according to Politico, a US political news website, on the 3rd local time, former US Secretary of Defense Mattis lashed out at US President Trump, saying "Trump is what I have seen in my lifetime. A president who is unwilling to unite the American people-not even pretending to try it."

  Rather than uniting American society, "On the contrary, he tried to divide us. We are witnessing the consequences of (Trump) deliberately over the past three years." Matisse said.

  This is Matisse's first public criticism of his former boss since Trump resigned in late 2018 due to Trump's decision to withdraw his troops from Syria.

  Mattis did not mention the names of other officials, but he also severely criticized the leaders of the Pentagon, including Secretary of Defense Esper.

  Matisse advocated that only in "very rare circumstances" and at the request of the governor can the army be deployed in the country. Esper also said on the 3rd that he does not support the use of active US military forces to enforce laws in the country to quell anti-racial discrimination demonstrations.

  Over the past week, large-scale protests have spread throughout the United States. The US National Guard Director Joseph Lengil said on the 2nd that more than 18,000 National Guard members have assisted in protests in 29 states and Washington, and the number is continuing to increase.

  On the evening of the 3rd local time, Trump retaliated against Matisse. He wrote on the social networking site: "Maybe the only thing Barack Obama and I have in common is that we all have the honor to fire the most overrated in the world. General Jim Mattis. I asked him for a resignation letter and it felt good. His nickname was'chaos', I didn't like it and changed it to'crazy dog'."
