The state of Arizona will not wait for the Biden administration to build a border wall on the U.S.-Mexico boundary and instead has chosen to go it alone, erecting its own state-funded barrier to stop an unprecedented flow of illegal immigrants.

Gov. Doug Ducey‘s top advisers announced in a call with reporters Friday morning that construction began “six minutes ago” on a portion of the Yuma, Arizona, border where gaps of land between Trump-era wall projects exist as a result of President Joe Biden’s January 2021 order to stop building the barrier.
