The pressure is finally being felt where it might do some good

U.S. House Rep. Kevin Yoder (R-KS), in a letter to Attorney General Jeff Sessions, is calling for the administration to halt the separation of families.

[...]

Yoder earlier on Monday responded to nearly 60 Johnson County officials asking him to put an end to the forced separation of families caught crossing the U.S. southern border illegally.

[...]

Yoder is the chair of the Homeland Security Subcommittee on Appropriations.

“As the son of a social worker, I know the human trauma that comes with children being separated from their parents. It takes a lasting, and sometimes even irreversible toll on the child’s well being,” Yoder stated in the letter. “That’s why I’m demanding that Attorney General Sessions halt the practice of family separation at the border immediately as Congress works toward legislative solutions.”

This report is inaccurate.

Yoder makes the claim in a tweet of demanding an end to the practice because of what he knows.  The letter to Sessions makes no such claim and does not demand.  It "asks".  Interesting mistake to make when the article reprints both the tweet and the letter.

There isn't even an implied threat in that letter* as to what might happen to DHS funding if Sessions doesn't halt the practice, but just that it was written shows that at least some Republicans are feeling the pressure.  And shows an admission that they know this policy rests squarely with the Trump administration and not the Democrats.

Some time ago, we saw and heard Jeff Sessions say that if people didn't want their children taken from them, they shouldn't be trying to cross the border illegally.  We knew then what was happening.  What sparked this new intense scrutiny and outrage?   Critical mass?
