President Donald Trump said in tweets this week that work is being done to build his proposed U.S.-Mexico border wall ― but he used months-old footage of repairs on existing parts of the barrier in an effort to support his claims. “We have just built this powerful Wall in New Mexico,” Trump tweeted Wednesday with a video showing workers and construction vehicles at the border. He said that portion of the wall had been completed on Jan. 30, some 47 days ahead of schedule, and that “many miles more” currently were being built.

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! #FinishTheWallpic.twitter.com/TYkj3KRdOC — Donald J. Trump (@realDonaldTrump) February 20, 2019

Trump retweeted the post on Thursday and added an all-caps caption saying the wall was under construction.

However, it’s not true that the wall featured in the video had been “just built.” The U.S. Army Corps of Engineers, whose logo appears in the bottom corner of the video Trump shared, actually produced the clip in September 2018, a spokesperson told veterans news website Task & Purpose. It shows “a replacement project” for a section of a barrier that was in place before Trump assumed office. Trump has declared a national emergency in an attempt to secure money for a wall along the U.S.-Mexico border. MSNBC’s Brian Williams also noted the discrepancy of Trump’s claim and the reality of the situation on Thursday’s broadcast of “The 11th Hour.”
