“Fox News host Chris Wallace relentlessly pushed Trump senior adviser Stephen Miller on Donald Trump‘s declaration of a national emergency on Sunday, and nailed him particularly hard by repeatedly asking for a single example of another president who has done what Trump has done,” Mediate reports.

“Wallace was all over Miller, challenging him to provide some explanation for how Trump’s national emergency is a national emergency, when Trump himself essentially admitted it wasn’t a national emergency. And when Miller tried to fend off the questions with talking points, Wallace peppered him with followups.”

John Cassidy: “Arguably, the most revealing exchange came when Peter Alexander, of NBC News, asked Trump to admit that the spending deal he was to sign later in the day gave him less money for his wall than he could have got before the government shutdown. Of course, Trump never admits anything. He insisted that he’d got ‘billions and billions of dollars for other things—port of entries, lots of different things’ from Congress. But, when it came to the wall, he went on, ‘they skimped.’ Then he added, ‘So I did—I was successful in that sense, but I want to do it faster. I could do the wall over a longer period of time. I didn’t need to do this, but I’d rather do it much faster.'”

“It will be interesting to see what the courts make of Trump’s admission that, when it came time to declare a national emergency, he didn’t ‘need to do this.’ At the least, it was good to get it on the record from his own lips. Inside the Reagan Administration there used to be a saying: ‘Let Reagan be Reagan.’ In the Trump Administration such a statement would be entirely redundant. The President lets it all hang out: the incoherence, the fabrications, the mendacity, the raging but delicate ego, the attention-deficit disorder, and, occasionally, the revealing shards of self-illumination. He just can’t help himself.”

New York Times: “The president’s move left Senate Republicans sharply divided, and it remains to be seen whether they will act collectively to try to stop Mr. Trump or how far into unchartered territory they are willing to follow a headstrong president operating with no road map beyond his own demands.”

“The Republican resistance to Mr. Trump’s emergency declaration was much more pronounced in the Senate than in the House, where a few Republicans — in the minority but more closely aligned to Mr. Trump — groused. But most of the conservative rank and file embraced it.”

“The good news out of this unconstitutional power grab is it will split off some Republicans from this wannabe Franco.”
