President Trump on Wednesday tweeted out a video showing construction vehicles hoisting segments of a wall on the New Mexico border.

“We have just built this powerful Wall in New Mexico. Completed on January 30, 2019 – 47 days ahead of schedule! Many miles more now under construction! #FinishTheWall,” he wrote in a post accompanying the video.

The video, which has been sped up, shows two backhoes, one digging a trench and another helping workers place the wall, which appears to be made of steel slats.

Trump declared a national emergency last Friday so that he can shift funds from other federal agencies to build his wall.

Congress had approved $1.3 billion for the wall, but Trump had demanded $5.7 billion.

Using the declaration to divert funds, Trump said he could come up with $8 billion.

Congress hasn’t approved any funds for new construction of the wall, but it has allocated money to replace or strengthen existing barriers.
