Michigan's Department of Civil Rights says immigrant children as young as three months of age have arrived in the state for temporary foster care placement after being separated from their parents at the U.S. border.

In a statement on Tuesday, the Michigan Department of Civil Rights denounced the Trump administration's zero tolerance immigration policy, which has resulted in the separation of migrant parents and children.

The statement also assured that the department was working to make sure children arriving in the state are well taken care of, are properly resettled and have their civil rights represented.

"This week, I have been in touch with various agencies and organizations working with these vulnerable children. We have received reports and are very concerned that the children arriving here are much younger than those who have been transported here in the past," Agustin Arbulu, the Department of Civil Rights' executive director, said in the statement.

"Some of the children are infants as young as three months of age and are completely unable to advocate for themselves," Arbulu continued. "While we commend the work of resettlement agencies in Michigan attempting to serve these children with dignity and compassion, nothing can replace the love, sense of security and care of a parent."

The announcement from the Michigan Civil Rights Department came on the same day The Associated Press reported that the Trump administration is running three "tender age" detainment facilities in Texas, where undocumented babies and toddlers are sent after being forcibly separated from their parents.

Thousands of children have been separated from parents as part of the Trump administration's zero tolerance policy, which mandates that all asylum seekers who cross the border illegally be prosecuted.

Members of Congress have introduced legislation to end the practice of separating families, while simultaneously urging Trump to unilaterally stop the separations.
