Politico reported the vice president will be joined by Homeland Security Secretary Alejandro Mayorkas as they travel to El Paso, Texas on Friday.
Earlier this month, she made her first trip overseas as vice-president - travelling to Mexico and Guatemala to hold talks about the migration crisis with the leaders of those two countries.
Harris' spokeswoman, Symone Sanders, said in a statement that the visit was part of Harris' "ongoing work" in addressing "the root causes of migration from El Salvador, Guatemala and Honduras".
Speaking to reporters at the White House on Wednesday, Press Secretary Jen Psakiaddressed questions from Fox News'Peter Doocy, and others, as to why she has now chose to visit the border despite months of claiming this was not her job. A record 178,000 undocumented migrants are said to have crossed over from the USA southern border this April, the highest total in more than two decades.
At a White House press briefing, Psaki also noted to reporters that she had "said here from this podium - and [Harris] has also said - that, when it was the right time, [Harris] may go to visit the border".
They've also slammed Harris, specifically, for not visiting the border after Biden tasked her with leading diplomatic efforts to address root causes of migration, a job Biden had as vice president during the Obama administration.
Former President Donald Trump, who plans a border visit on June 30, said in a statement: "If (Texas) Governor (Greg) Abbott and I weren't going there next week, she would have never gone!"
After Biden reversed or altered a number of key Trump-era policies upon entering office, the border situation worsened quickly. And if you look just to a couple of months ago when 6,000 children were in border patrol facilities, we are now at the point where there is far less than 1,000. Illegal border crossings hit 180,034 in May, with 51,000 others avoiding capture. Republicans have zeroed in on the increased number of migrants heading to the border as a line of attack against the Biden administration, repeatedly calling it the "Biden border crisis".
Administration officials have defended the border policies, claiming they've made the immigration system "more humane".
Republicans in Congress said Harris will see firsthand what the administration's policies have wrought.
President Joe Biden assigned Harris the task of addressing the root causes of migration of thousands of people from El Salvador, Guatemala and Honduras who cross the US border from Mexico.
