President Joe Biden on Wednesday said he’d asked Vice President Kamala Harris to lead the administration’s efforts to stem migration at the U.S.-Mexico border. “This new surge we are dealing with now started in the past administration but it is our responsibility” to deal with it now, Biden said at a White House event, according to a pool report. Harris will work with other nations to strengthen immigration enforcement at borders, Biden said. Republicans have dubbed a surge of migrants at the southern border “a Biden border crisis,” and the president is likely to field multiple questions about the issue at his first news conference Thursday.
