'Why are you laughing?' GOP lawmaker flips out on witness during tense hearing

Rep. Anna Paulina Luna (R-FL) flew into a rage at Cato Institute immigration expert David Bier on Wednesday after he openly mocked her defense of the Trump administration's policies of separating migrant children from their parents.

During a hearing on immigration in the House of Representatives, Luna slammed Bier's contention that the Trump administration inflicted psychological trauma on migrant children by separating them "from their quote-unquote-parents."

This apparently caused Bier to start laughing, which drew an angry reaction from Luna.

"Why are you laughing?" she demanded to know.

"Because you said, 'quote-unquote parents,' as if they weren't really their parents," he replied.

"You have no idea!" she shot back.

"I do have an idea!" replied Bier.

"You have no idea if these people are their ... parents or not," said Luna.

"No, we do," insisted Bier.

"Oh really, are you psychic?" Luna demanded to know.

Bier tried to get Luna to read an inspector general's report outlining documented family separations, but Luna wouldn't have any of it.

"You have no idea what you are doing and you are hurting these children!" she said.

In fact, it has been confirmed the Trump administration forcibly separated more than a thousand children from their parents, and the Biden administration so far has had success in reuniting hundreds of them.
