Natalie is spearheading a new campaign calling on U.S. lawmakers to stop tearing families apart as authorities crack down on illegal immigration.

She has joined forces with activists at the National Domestic Workers Alliance to slam the new policy via a MoveOn petition, which will be delivered to Secretary of Homeland Security Kirstjen Nielsen, and members of the U.S. Congress.

“This shockingly cruel, traumatic, and inhumane practice has no place in our country,” Natalie shares in a statement. “It must be stopped immediately, and without holding these children hostage to pass other anti-immigrant policies.

“We must speak loudly enough, and in large enough numbers, that the media stays focused on this story.

“I’ve joined the National Domestic Workers Alliance to launch this petition. Please sign it and stay tuned for more ways to help these families.”

More than 320,000 people had added their names to the campaign until now.

Natalie isn’t the only star to speak out against the controversial illegal immigration policy – Bette Midler, singer John Legend and his wife Chrissy Teigen, filmmaker Ron Howard, actresses Evan Rachel Wood and Alyssa Milano, and country singer Willie Nelson are among the celebrities to blast the Trump administration in recent days, while Hollywood veteran Kevin Costner expressed his disgust during an appearance on talk show The View last Tuesday.
