President Joe Biden said on Thursday that he couldn’t stop federal funds from being used to build sections of the U.S.-Mexico border wall after Congress had appropriated the money, adding that he still does not think such a barrier works. “I can’t stop that,” he said. Earlier in the day, the Biden administration announced that it was waiving 26 federal laws to permit more border wall construction in southern Texas. The move is a shift for Biden, who campaigned against the policy embraced by former President Donald Trump. Both are seeking the presidency again in 2024.
