"Sometimes truth transcends party," Obama said in a tweet responding to Bush, who was sharing her op-ed for the Washington Post.

 

 

Former President Obama quickly retweeted his wife's post. 

It is rare for Michelle Obama to weigh in on policy issues, such as the Trump administration's migrant policy.

She criticized the administration's policy of delaying federal rules on school lunches last year and has been critical of women who voted for Trump. 

Obama's tweet comes after Bush ripped the policy in her Post op-ed on Sunday, calling it "cruel" and "immoral." 

“I live in a border state,” Bush wrote. “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.”
