For nearly four years, the US is suffering its worst border crisis in the world history, said Donald Trump, former president and Republican candidate for the US presidency.
Thursday's claims by Trump came ahead of his Democratic rival Vice President Kamala Harris's visit to the US-Mexico border down South on Friday.
"For nearly four years, we have been going through the worst border crisis in the history of the world. There's never been anything like it that has brought untold suffering, misery, and death upon our land. The architect of this destruction is Kamala Harris," Trump said in a news conference in New York.
"When you look at the four years that have taken place after being named border czar, tomorrow Kamala Harris will be visiting the southern border that she's completely destroyed. Why in the world would she go to the border now, playing right into the hand of her opponent? There can be no justification for what she's done. Nobody's saying, oh, gee, she's done a fabulous job. She's done the worst job probably in the history of any border, not just our border. She keeps talking about how she supposedly wants to fix the border," Trump said.
"We would just ask, why didn't she do that four years ago? She has no plans, no talent, no ability to do it. I'm here today to present you with facts and only facts about how comrade Kamala Harris willfully threw open our border, helping virtually to destroy our country. Our country has never been under siege like this," Trump said.
Four years ago, he said, Harris inherited the most secure border in US history with the lowest illegal immigration on record.
