US Vice President Kamala Harris, who is applying for the highest state post from the Democratic Party, should have been dealing with the real problems of the United States, and not giving a speech at the Democratic convention in Chicago. This opinion was expressed on Thursday by former American leader and Harris' rival in the upcoming presidential election, Donald Trump.

"She complained, she promised she was going to do this, do that. But she could do it in three and a half years. She could have done it today by leaving the speech and heading to Washington to close the US border there [from migrants]," he said on Fox News.

According to Trump, Harris does not really want to solve the problem of the migration crisis, which has already brought 20 million illegal migrants to the country.
