President Donald Trump believes he has worked out a killer trade deal with Mexico and Canada -- but one former Mexican diplomat tells Storm Lake Times columnist Art Cullen that the damage done to the relationship between the countries will have lasting ramifications for years to come.

Jorge Guajardo, who served for six years as Mexico's ambassador to China, recently explained to Cullen that Trump's erratic behavior has shown his country that it must look for other major trading partners so it doesn't run the risk of getting burned by the United States again.

On Wednesday, President Donald Trump continued to attack the young congresswomen of color nicknamed "The Squad," after he was criticized for saying the women should go back to their own countries, even though all four are U.S. citizens. Now, he's doubling down.

On Twitter Wednesday he called the women "left-wing cranks." He added that they were free to leave if they don't like America.

Raw Story spoke with Dr. Bandy X. Lee about the President's racist tirades against Alexandria Ocasio-Cortez (D-NY), Ilhan Omar (D-MN), Rashida Tlaib (D-MI) and Ayanna Pressley (D-IL).

Lee is a forensic psychiatrist and an expert on violence at Yale School of Medicine. She helped launch a public health approach to global violence prevention as a consultant to the World Health Organization and other United Nations bodies since 2002. She is author of the textbook, “Violence: An Interdisciplinary Approach to Causes, Consequences, and Cures,” president of the World Mental Health Coalition, and editor of the New York Times bestseller, “The Dangerous Case of Donald Trump: 37 Psychiatrists and Mental Health Experts Assess a President.”

President Donald Trump exhibits a verbal tic that gives away some of his biggest whoppers.

The president tells demonstrable lies on a daily basis, but it's a "flashing red light" that he's lying when he recounts someone calling him "sir," according to CNN fact-checker Daniel Dale.

"Trump has told false 'sir' stories on all manner of subjects: health care, the Middle East, the courts, unions and -- just last week -- both tariffs and social media," Dale wrote. "But no genre of Trump story is more reliably sir-heavy than his collection of suspiciously similar tales about macho men breaking into tears of gratitude in his presence."
