Federal contractors are building eight prototypes of President Trump’s proposed border wall with Mexico — including this one as seen from the Mexican side of the border near Tijuana.

Authorities kept the press and onlookers nearly three miles away on the American side, but the prototype — which appears to be about 30 feet tall — can be seen up close from Mexican territory.

The development suggests Trump is inching closer to fulfilling one of his campaign promises — though there is no guarantee that it will be fully funded or survive court challenges.

A complaint filed last week by California Attorney General Xavier Becerra, a Democrat, mirrors two others by environmental groups that allege the administration overstepped its authority to speed up construction.
