Boris Johnson, the former U.K. foreign secretary, said Donald Trump‘s Twitter attack on Democratic congresswomen of color was „totally unacceptable,“ adding that he could not understand why the U.S. president had made them.

„It is totally unacceptable in a modern multi-racial country which you’re trying to lead,“ he said of U.S. president‘s remarks at a Conservative party leadership debate hosted by the Sun newspaper and Talk Radio, although he refused to condemn the tweets as „racist.“
