As an effort to head off Senate approval for Nancy Pelosi’s emergency-declaration rebuke, it’s a day late and a dollar short. As prep for the PR needed to prevent a veto override, though, this series of clips from the White House comms team could be right on time. After the Senate votes as expected to end the emergency Donald Trump declared last month, Trump says he’ll veto it now that it’s clear that action will be necessary:

The aside was to Irish PM Leo Varadkar, who has been battling with the UK over the hard-border issue created by Brexit. Talk about going from the fire to the frying pan …

Earlier this morning, Trump appeared to shift a bit on Republican efforts to limit presidential authority under the National Emergencies Act. He had earlier rebuffed efforts to replace Pelosi’s bill with a compromise from Mike Lee, apparently annoyed at having to give up the authority granted to his office in 1976 and used in 59 other instances. With more Senate Republicans shifting to support the Pelosi bill, Trump tried to woo them back with promises of later support for such reforms:

Donald J. Trump

@realDonaldTrump

….If, at a later date, Congress wants to update the law, I will support those efforts, but today’s issue is BORDER SECURITY and Crime!!! Don’t vote with Pelosi!

Too little too late, Senate Republicans responded:

Senate Republicans were caught off guard by President Trump’s tweet that he would support future changes to limit his authority on national emergencies, according to multiple aides — but it’s unlikely it will have a significant effect on the final vote count.

“Too little, too late,” one senior GOP aide said. It may sway a few on-the-fence senators, but the resolution is still expected to pass with a number of GOP defections.

That means that the White House has to begin the fight to keep either chamber from overriding his veto. Yesterday, they began publishing a series of short videos intended to convince Americans of the crisis at the border and the need for emergency executive action to stop it. The effort has continued into this afternoon on Twitter. Here’s a brief taste of the output:
