Chrissy Teigen took President Donald Trump and his administration to task on social media Thursday, voicing her concern on the treatment of immigrant families and to announce her donation to the American Civil Liberties Union (ACLU) on Trump's birthday.

"John and I are outraged to see and hear the horror stories of immigrant families seeking asylum and refuge in America being ripped apart due to inhumane policies of the Trump administration," she wrote in an Instagram post.

Teigen, who welcomed her second child last month, added that the stories she's heard "go against everything we believe this country should represent."

"The ACLU is committed to defending the rights and humanity of these vulnerable families. In addition to fighting for immigrants' rights, criminal justice reform, LGBT rights, 1st amendment rights and holding the Trump administration accountable whenever possible," she continued.
