The American Civil Liberties Union says it intends to sue over President Joe Biden's plan to enact immediate significant restrictions on migrants seeking asylum at the U.S.-Mexico border. Biden signed the proclamation Tuesday as the White House tries to neutralize immigration as a political liability ahead of the November elections. Biden's order would bar migrants from being granted asylum when U.S. officials deem the southern border to be overwhelmed. The ACLU says an asylum ban “is illegal.” The Democratic president has contemplated unilateral action for months, especially after Republican lawmakers rejected a bipartisan security deal at the behest of presumptive GOP presidential nominee Donald Trump. Trump says Biden has surrendered the southern border.
