Michelle Obama on Monday retweeted another ex-first lady’s post opposing President Trump’s zero-tolerance policy of separating the children of asylum seekers caught entering the US illegally.

“Sometimes truth transcends party,” she wrote along with a post from Laura Bush, wife of former President George W. Bush.

“I live in a border state. I appreciate the need to enforce and protect our international boundaries, but this zero-tolerance policy is cruel. It is immoral. And it breaks my heart,” Laura Bush had tweeted Sunday along with a link to an opinion piece she had written for the Washington Post critical of the child separations.

Criticism of the commander-in-chief over the policy escalated Monday from both sides of the aisle, as well as from religious groups and advocates for immigrants.

But Trump remained defiant, branding immigrants “thieves and murderers and so much else” and declaring that “the United States will not be a migrant camp and it will not be a refugee holding facility. Not on my watch.”
