President Joe Biden has expanded a humanitarian parole program  leading to a significant increase of migrants entering the United States illegally each month. As a result, 20 states have geared up to sue the Biden administration.

Tuesday, 20 Republican states and conservative legal group America First Legal, announced their plans to sue the White House over the legality of the administration’s parole program. The program “allows up to 30,000 migrants from Haiti, Nicaragua, Cuba, and Venezuela into the homeland each month” reports Foreign Desk News.

Reports shoot the lawsuit was filed by Texas, the America First Legal and the other states in the Southern District of Texas in hopes to block the parole program.

Foreign Desk News reports of the history:

In October, the administration announced the program for Venezuelans, allowing a limited number to fly directly into the U.S. as long as they had not entered illegally, had a sponsor already, and passed certain checks. In early January, President Biden announced that the program would expand to include Haitians, Nicaraguans, and Cubans, allowing up to 30,000 a month into the U.S.

The program also allows migrants to receive work permits and a two-year authorization to live in the U.S. and was announced alongside an expansion of Title 42 expulsions to include those nationalities.

In the lawsuit, the plaintiffs argue that the program is unlawful given the “exceptionally limited” parole power the federal government has, adding that they have up to 360,000 migrants that could be allowed into the homeland a year.

The suit’s focus is on the limits placed on parole by Congress, saying that the authority is to be used on a “case-by-case basis for urgent humanitarian reasons or significant public benefit.”

“Every state in America, especially border states like Texas, is being crushed by the impacts of illegal immigration,” Texas Attorney General Ken Paxton said in a statement to Fox News Digital.

“The Biden open borders agenda has created a humanitarian crisis that is increasing crime and violence in our streets, overwhelming local communities, and worsening the opioid crisis. This unlawful amnesty program, which will invite hundreds of thousands of aliens into the U.S. every year, will only make this immigration crisis drastically worse.”
