Trump’s first firing of his Cabinet colleagues comes days after major media outlets declared that he has lost the November 3 elections to Democratic presidential candidate Joe Biden.

Trump’s firing comes days after Esper in an interview told The Military Times that he was not a “yes man” for the president.

“My frustration is I sit here and say, Hm, 18 Cabinet members. Who’s pushed back more than anybody? Name another Cabinet secretary that’s pushed back,” he told The Military Times.

“Have you seen me on a stage saying, ‘Under the exceptional leadership of blah-blah-blah, we have blah-blah-blah-blah?'” he said.

The visit to India to attend the 2+2 ministerial meeting was Esper’s last foreign travel as defence secretary.
