On Friday's broadcast of "CNN News Central," Rep. James Clyburn (D-SC) said that he has "no idea" how to explain why 2024 Democratic presidential candidate Vice President Kamala Harris hasn't visited the border in three years, but "she went to the countries of origin to try and find out exactly how we could tackle this problem from the very origin of it rather than hang out at the border." And "I don't know that visiting the border is all you need to do to tackle this problem."
