Vitiello made the remark one day before Homeland Security Secretary Alejandro Mayorkas will visit Guatemala.
The Department of Homeland Security (DHS) announced that Mayorkas will travel to the Northern Triangle country on Tuesday and Wednesday and will "meet with counterparts in the government of Guatemala regarding shared priorities."
Mayorkas "will also meet with in-country members of the DHS workforce and key DHS partners," the statement maintained.
Amid a border crisis that has seen hundreds of thousands of migrant encounters in recent months, the Biden administration has established significant emphasis on the "root causes" of the crisis like violence, climate change and poverty in Central America and Northern Triangle nations like Guatemala.
The trip comes almost a month after Vice President Kamala Harris visited Guatemala as part of a trip to the area, in which she was met with criticism for not having visited the border as part of her position in leading diplomatic talks to tackle the "root causes" of the migrant crisis.
While she highlighted those root causes and unveiled a number of measures to tackle them, her visit was complicated by Guatemalan President Alejandro Giammattei, who partially accused the Biden administration of encouraging the surge.
"Working with Guatemala, working with The Northern Triangle on governance and anti-corruption activities, that’s all well and good, but that’s not going to stop the surge that’s occurring on the border right now," Vitiello claimed on Monday. "We’ve encouraged people to send or bring their children to the border and the root cause of the chaos is the reversal of the policies."
President Biden dismissed a number of his predecessor's immigration policies, which involved wall construction and having asylum seekers stay in Mexico rather than in the U.S. while they wait for their cases to be heard. The moves have led to a record surge in migrants, including unaccompanied minors, that has strained capacity at immigration facilities.
A White House spokesperson did not immediately respond to a request for comment.
Vitiello further claimed on Monday that cartels are benefiting from the migrant surge.
"People who come up to the border and the people who are smuggled into the pipeline, they’re controlled by smugglers and cartels," Vitiello said. "They’re the one that are getting over because of this surge at the border."
