President Biden is putting Vice President Harris in charge of addressing the migrant surge at the U.S.-Mexico border, senior administration officials announced on Wednesday.

Why it matters: Just as President Obama tasked Biden with fixing the U.S. economy after he assumed office in 2009, Biden is putting his own vice president in charge of a problem threatening to overshadow the new administration's own successful launch.

• Harris will lead efforts with Mexico, Guatemala, Honduras and El Salvador to manage the flow of unaccompanied children and migrant families arriving at the border in numbers not seen since a surge in 2019.
• "Starting today, the Northern Triangle nations and Mexico will know there was one senior official dedicated to this effort. To be very clear, this is an important task," a senior administration official told reporters during a conference call.
• It was held just an hour before a White House event with Biden, Harris, Homeland Security Secretary Alejandro Mayorkas and Health and Human Services Secretary Xavier Becerra.

The announcement and high-level meeting, coming the same day the White House arranged a trip for senior aides and member of Congress to South Texas, illustrated the breadth of the administration's efforts to get control of the problem.

• Republicans say Biden is to blame for refusing to reinstate a Trump-era policy to expel unaccompanied minors, as well as more accommodating language the president's own press secretary concedes is connected to its humanitarian values.

What they're saying: "President Biden said during the transition, whatever the most urgent need, he would turn to the vice president," one of the three officials briefing reporters said, "and today he is turning to the vice president."

• The first goal will be stemming the flow of illegal migrants to the U.S.
• In a broader context, Harris also will work on establishing a strategic partnership with the Central American countries "based on respect and shared values," another official said.
• The work will be conducted with the understanding that "these countries are our friends and our neighbors. They are members of our shared community of the Americas and within the western hemisphere."

Details: One official said Harris spoke Wednesday morning with Ricardo Zúñiga, the State Department’s special envoy to the Northern Triangle.

• Zúñiga and other top border officials left earlier this week for Mexico and planned to go on to Guatemala with the goal of addressing local problems fueling the migration north.
• They include lax responses to the coronavirus pandemic, rampant crime, as well as the after-effects of two hurricanes that blew through the region.
• The Biden administration has discussed increased aid to address some of these root concerns.

The bottom line: "The people of the Northern Triangle certainly deserve to experience freedom and opportunity, and be able to access protection within the Northern Triangle," one official told reporters.

• "They shouldn't have to come to the United States to seek that freedom and opportunity, and that's what she'll be working towards."
• Among the items to tackle are local corruption and ways to improve local economies.
