* Meagan Flynn reports on the latest scandal of the Trump administration:

The image kept replaying in attorney W. Warren Binford’s mind after she left a migrant detention facility last week in Clint, Tex., where hundreds of children were held: The 15-year-old mother, her baby covered in mucus.

It seemed no matter how many times she washed the sick baby’s clothes in the sink she couldn’t get them clean. There was no soap. And when she tried to find baby food, there was none of that, either. All they had was instant oatmeal for breakfast, instant soup for lunch and a frozen burrito for dinner, “every single day,” Binford said.

Child care was not the forte of U.S. Customs and Border Protection, Binford could see. Here, in a warehouse filled with filthy kids who had not bathed in days, some with lice and influenza, it was kids taking care of kids.

“We were just horrified,” Binford, director of the clinical law program at Willamette University, told The Washington Post, adding: “It was just horrendous, the stories that we were hearing.”

And the administration’s answer is not “We’ll fix this” but “It’s the Democrats’ fault.”

* William Branigan and Erin Cunningham report that the president is determined to look tough on Iran:

President Trump, warning that U.S. “restraint” has limits, signed an executive order Monday imposing additional economic sanctions on Iran in apparent retaliation for the downing of a U.S. drone last week.

Trump said the new “hard-hitting” sanctions will deny Iran’s supreme leader, Ayatollah Ali Khamenei, and other top officials access to financial resources.

“We will continue to increase pressure on Tehran,” Trump said in an Oval Office signing ceremony attended by Vice President Pence and Treasury Secretary Steven Mnuchin. “Never can Iran have a nuclear weapon.”

If only we could have made some sort of multinational agreement to restrain their nuclear program. Oh wait...
