Michelle Obama blasted Donald Trump as an incompetent president who displays an “utter lack of empathy,” as the former first lady addressed the opening night of the US Democratic convention Monday.

“Whenever we look to this White House for some leadership, or consolation, or any semblance of steadiness, what we get instead is chaos, division and a total and utter lack of empathy,” the wife of former president Barack Obama said in a blunt rejection of the Trump administration.

“Let me be as honest and clear as I possibly can: Donald Trump is the wrong president for our country,” she added.

Earlier, ex-President Barack Obama said Joe Biden made a brilliant choice of Senator Kamala Harris as a running mate in this year’s United States Presidential Election scheduled to hold in November.

Obama said, “When you’re in the Oval Office, weighing the toughest issues, and the choice you make will affect the lives and livelihoods of the entire country – you need someone with you who’s got the judgment and the character to make the right call. Someone whose focus goes beyond self-interest to consider the lives and prospects of others.

“Joe Biden nailed this decision. By choosing Senator Kamala Harris as America’s next vice president, he’s underscored his own judgment and character. Reality shows us that these attributes are not optional in a president. They’re requirements of the job. And now Joe has an ideal partner to help him tackle the very real challenges America faces right now and in the years ahead.
