An immigrant from Haiti who was released into the United States by the Biden administration has been arrested for the rape of a disabled child. 

26-year-old Cory Alvarez was charged in Massachusetts for the assault of a 15-year-old girl at a migrant shelter in the Boston area. It's not clear if the victim is also a migrant.

The horrific crime is the latest violent offense to highlight the impact of the southern border crisis and the government's failure to vet migrants.

Migrant arrested in sexual assault

Alvarez pled not guilty to aggravated rape of a child after his arrest Thursday.

The Comfort Inn in Rockland, Massachusetts where the alleged crime took place is part of a migrant housing program, the Plymouth County District Attorney's Office said.

The Department of Homeland Security acknowledged the "heinous" crime, which is believed to have occurred after the suspect was paroled into the country through a Biden administration program.

The Biden administration's controversial parole program allows 30,000 migrants per month from the troubled nations of Cuba, Nicaragua, Haiti, and Venezuela to bypass the ordinary process and enter the country legally for two years.

Last month, a 26-year-old Venezuelan, Jose Ibarra, was arrested for the murder of a Georgia nursing student, Laken Riley, stirring national outrage.

"Safe and orderly"

Alvarez entered the country last June via New York and was supposed to join a sponsor in New Jersey.

The suspect's Haitian origin is concerning because of the political crisis brewing in Haiti, which has spiraled into gang warfare. Many are concerned that the crisis there will drive an influx to the United States, putting further strain on an already overwhelmed border.

House Republicans are demanding more information about the government's vetting of Alvarez from the Department of Homeland Security, whose secretary Alejandro Mayorkas has faced criticism for his handling of the border.

Last week, Mayorkas praised the parole program as a "safe and orderly way to reach the United States" after a federal judge rejected a Republican lawsuit challenging the program.

"These processes — a safe and orderly way to reach the United States — have resulted in a significant reduction in the number of these individuals encountered at our southern border," he said.

With immigration rating as one of the top concerns of voters, Biden has pledged to continue blaming Republicans for the collapse of a "bipartisan" reform. Republicans have fired back that Biden can control the border on his own but refuses to do so.
