The initial standoff began July 27, with activists occupying a tree known as the "Grandmother" to obstruct President Trump's $46.5 billion expansion of the double border wall. During the occupation, which lasted more than two months, Frontlines TPUSA reported that proponents of an "autonomous zone" assaulted a staff member and slashed vehicle tires. While the CBP's removal of the first tree temporarily cleared the area, the move to a new site indicates continued efforts to disrupt the federal security project.
