Former U.S. President Donald Trump criticized Vice President Kamala Harris' record on immigration, once more labeling her as a "Border Czar" in an update on his Truth Social media platform.
Trump claimed that Harris "never visited the Border," in a likely reference to the U.S.-Mexico perimeter, which has seen record levels of illegal crossings in the past year.
Republican rivals are likely to lash Harris with further criticism on immigration — a key concern for U.S. voters — with Trump alleging that the vice president's performance "gave us the WORST and MOST DANGEROUS Border anywhere in the World."
Back in 2021, Harris was tasked with helming the diplomatic mission to address the "root causes of migration in Central America" — but not to oversee or enforce immigration policy, or the border itself.

Harris also made her case against the rival candidacy of former U.S. President Donald Trump, who has once more gained the Republican nomination.
"This election will present a clear choice between two different visions. Donald Trump wants to take our country back to a time before many of us had full freedoms and equal rights. I believe in a future that strengthens our democracy, protects reproductive freedom and ensures every person has not just the opportunity to get by, but to go ahead," she said.
