Minnesota Attorney General Keith Ellison joined 21 other state attorney generals in suing President Donald Trump over an executive order to end birthright citizenship.

A federal judge temporarily blocked the executive order Sunday, which Trump plans to appeal, the New York Times reported. 

Birthright citizenship, a provision of the 14th Amendment of the Constitution, grants citizenship to any person born in the U.S., regardless of where their parents were born.

Trump’s executive order goes against the constitution, Ellison said in a statement.

“For more than 125 years, the Supreme Court has clearly interpreted the Fourteenth Amendment of the U.S. Constitution to eliminate any doubt or confusion that anyone born in the U.S. is automatically a U.S. citizen,” Ellison said in the statement.

Under Trump’s executive order, children born in the U.S. to people not lawfully in the country, and children born in the U.S. but whose parents were only in the country temporarily under a tourism or student visa, would not be citizens. 

According to Ellison’s statement, the end of birthright citizenship would restrict people’s access to a social security number, the ability to participate in federal programs and the right to vote. 

“I am using the power of my office and the law to join with other state attorneys general from coast to coast to quickly and clearly bring suit to stop this unprecedented, blatant breach of the Constitution by a President,” Ellison said.

The suspension of refugee admissions, asylum applications at the southern border and the attempt to prohibit birthright citizenship has stoked fear in immigrant and refugee communities, according to a statement from the Immigrant Law Center of Minnesota.

In addition to individuals losing access to federal programs, the executive order would also cause states like Minnesota to lose federal funding for programs such as Medicaid and foster care, according to Ellison’s statement.

On Jan. 26, federal Judge John C. Coughenour temporarily blocked the executive order, calling it “blatantly unconstitutional,” the New York Times reported. The decision blocks the executive order for 14 days and is renewable once it expires. 

Since his return to the White House, Trump has signed multiple executive orders regarding citizenship and immigration, including an order to indefinitely suspend refugee resettlement.

The International Institute of Minnesota, a refugee resettlement agency in the Twin Cities, is among the organizations impacted by these orders. 

According to an International Institute press release, the institute received an order on Friday to immediately stop helping new refugees through federal funding. The order impacts refugees who arrived in Minnesota in the last 90 days.

“The halt to existing funding could be catastrophic for refugees who recently arrived in Minnesota,” Jane Graupman, executive director of the International Institute of Minnesota, said in the statement. “The goal of our work is to help clients become self-sufficient as quickly as possible. Without providing support in these critical first months of arrival, people are essentially left stranded.”
