The Note: The limits of Trump’s powers made evident The president’s own party, even his own family, pushed him into retreat.

The TAKE with Rick Klein

The first lady’s jacket may suggest otherwise, but this week the American people answered the question emphatically: They care.

Just as important, their voices mattered. It suggests that the issues highlighted in recent days won’t fade with the news cycle, as new power dynamics settle in for Washington and beyond.

The consensus view among the president’s allies is that Donald Trump’s instincts failed him. It happened somehow slowly and quickly at the same time. The administration contradicted itself in spectacular fashion, as sights and sounds brought the real world into the light, providing a counter to spin and misinformation.

It’s not over yet, and won’t be over even after the House votes on a broader immigration measure pushed to next week in hopes of avoiding failure. The president miscalculated at this moment but remains confident that the approach that helped win him the White House — up to and including "zero tolerance," whether or not families are separated — can resonate again.

But the president’s own party, even his own family, pushed him into retreat. Trump may be confident as ever in his own powers, but their limits were made evident in dramatic fashion.

The RUNDOWN with MaryAlice Parks

Arguably, this week was the latest example of a country pushed to its limits under the Trump administration.

This presidency saw protests spring up at airports around the country in the days after the so-called "Muslim travel ban." Democrats and critics took to the streets when a confusing executive order meant turning people away from their families unannounced.

Fast-forward to last summer and the outcry over the president’s "very fine people on both sides" comments following a white nationalist march in Charlottesville.

In December, the country saw the limits of the Republican Party in a state as red as Alabama. The cynical view of that special Senate election: accusations of child molestation were a red line.

The immigration crisis that has played out over the last few weeks feels, too, like a test of the country in a way – a portion of the public pushed to the limit. The reality (and audio) of crying children kept away from their parents in government facilities was simply too much.

President Trump remains incredibly popular among Republicans, and polls showed a majority of GOP voters approved of the family separation policy, at least early on, before the images and sounds emerged.

So, maybe this era shows the limits for some — and the determination and party entrenchment of others. And while limits can be telling, what about everything up to the line?

The TIP with Benjamin Siegel

What appeared to be a turning point in the immigration crisis has now been put off — as has happened so often before with this politically vexing issue.

After failure seemed certain, House Republicans on Thursday night again delayed a vote on a compromise immigration bill, until next week, but emerged from a two-hour, closed-door meeting with confidence — members saying the group was having productive conversations.

Republicans are considering adding provisions expanding the use of E-Verify — the system that allows employers to check if new hires are legally allowed to work in the U.S. — and adding visas for agricultural guest workers, a concern of Republicans in farm districts.

Said Oklahoma GOP Rep. Tom Cole: "People are trying to work towards getting to 218."
