GOP wants to hold Harris’s immigration record against her - what did she do?

As vice-president, Harris was handed a daunting mission at the onset of her term: to address the "root causes" of migration from the northern triangle countries of Guatemala, Honduras and El Salvador. But at no point was she put in charge of border policy. That is the responsibility of the Homeland Security secretary, Alejandro Mayorkas, who was with Harris when she visited the border in June 2021, three months after she was given the assignment. 

Instead, Harris's mandate, as laid out by the president, was to meet with government officials and private sector partners to tackle enduring problems in the region, such as poverty, violence and a lack of economic opportunity, that drive people to migrate from their home countries to the United States, said Theresa Cardinal Brown, a senior adviser of immigration and border policy at the Bipartisan Policy Center. 

"It was a diplomatic and development focus," she said, "not a border focus."
