Dana Milbank writes in The Washington Post:

Babies are seized from their mothers’ arms. Photographs show their anguish. News reports describe their cages. A recording captures their wailing and a U.S. border official’s cold mockery. A defiant President Trump falsely blames others for the misery he created.

And Republican lawmakers respond as they often have: They hold another hearing about Hillary Clinton’s emails.

But they have run this play too many times before.

Just 29 seconds into Tuesday’s hearing on the defeated Democratic 2016 presidential nominee and her emails, Rep. Jerrold Nadler (N.Y.), top Democrat on the Judiciary Committee, interrupted to point out that something more important needs attention.

“We have seen the pictures of immigrants ripped apart from their parents at the border. These children are not animals,” he said. “They are children who have been forcibly removed from their parents in our name.”

Republicans on the committee tried to silence Nadler with calls of “order!”

Nadler spoke over them: “The United States should be better than this. We should not put children in cages.”

“Regular order!” called out Rep. Bob Goodlatte (R-Va.), chairman of the Judiciary Committee.

Rep. Trey Gowdy (R-S.C.), chairman of the Oversight and Government Reform Committee, said Nadler “has been given more time than would have been afforded the other side, had we pulled something like that.”

Ah, so it’s “regular order” to have the umpteenth hearing about a now-private citizen’s emails, but you’re “pulling” a stunt if you talk about the Trump policy under which border guards are reportedly telling parents they are taking children “for a bath” and the children never return.

No, Republicans, your “regular order” is out of order.
