By SEUNG MIN KIM and COLLEEN LONG (Associated Press) WASHINGTON (AP) — The White House is considering using provisions of federal immigration law repeatedly tapped by former President Donald Trump to unilaterally enact a sweeping crackdown at the southern border, according to three people familiar with the deliberations. The administration, stymied by Republican lawmakers who rejected a negotiated border bill earlier this month, has been exploring options that President Joe Biden could deploy on his own without congressional approval, multiple officials and others familiar with the talks said.
