On Tuesday evening, President Donald J. Trump sent out a tweet about his trip to San Diego to see the border wall prototypes. His message said the wall is vitally important to the country, and that it must be funded.

Trump included a video montage of his California visit, including images of him meeting with U.S. Customs and Border Protection agents.

The message Trump included with the video read: If we don’t have a wall system, we’re not going to have a country. Congress must fund the BORDER WALL & prohibit grants to sanctuary jurisdictions that threaten the security of our country & the people of our country. We must enforce our laws & protect our people! #BuildTheWall
