EXCLUSIVE: DHS test of steel prototype for border wall, Trump's preference, showed it could be sawed through.

We've obtained a never-before-seen photo.

Our report, with @JuliaEAinsley. nbcnews.com/politics/immig…

Here’s the type of steel slat barrier the president wants (complete with the pointy top) that we have learned can be cut through with a household saw.

Tune into @MSNBC for more through the day.

Trump has long struggled to understand the reality of life along the border.

Now another reality check, exclusive to @NBCNews: the steel slat barrier he's chosen as border wall was sliced through with a saw when tested.

I shared the details with @WillieGeist on @Morning_Joe.

NEW: @realDonaldTrump responded to the story from @JuliaEAinsley and yours truly about the fact his steel prototype was *sliced open* with a saw.

Watch to see what he said.

Like much of what he says about the border his response wasn't true or accurate as I told @HallieJackson.

Trump came down here to Texas to make the case for a steel border wall.

But we exclusively obtained a photo of his steel prototype, which was sliced wide open with a saw.

Our @NBCNightlyNews report.

Shout out to @jeanguerre and @KPBS. As we point out, she originally broke the story that Trump's prototypes had been breached, before we obtained the photo, when they FOIA'd test results last year.

Here's her report from September. kpbs.org/news/2018/sep/…

Give her a follow.
