More than 50 Democrats in the state Assembly on Thursday signed onto a letter to President Donald Trump and Attorney General William Barr urging the federal administration improve conditions at detention facilities holding migrant families near the southern border.

Press reports and an inspector general investigation at facilities have described overcrowding and unsanitary conditions at the detention facilities.

In the letter, the lawmakers called the issues raised at the detention facilities a humanitarian crisis.

“While we recognize the need for comprehensive immigration reform, there is an immediate humanitarian crisis to address,” the letter states. "The administration should reverse course without delay to end the overcrowding at detention facilities, stop the mass deportations, and stop the separation of families.”

The letter comes as federal immigration enforcement officials are planning raids around the country on Sunday, potentially deporting thousands of undocumented immigrants and their families in the process.

The letter from the state Assembly was released by Assemblywoman Pat Fahy, a Democrat from Albany.

“We’ve all seen the horrifying images and videos coming out of detention facilities located on our southern border – but the DHS Inspector General report last week prompted an immediate call to action we cannot ignore,” she said in a statement.

“The Trump Administration’s directives and policies have directly fueled the humanitarian crisis at our southern border. These practices only exacerbate an already extremely precarious situation on our southern border, and run contrary to the very fundamental values that unite us as Americans.”
