Watch live: President Biden delivers remarks at U.S.-Mexico border

President Joe Biden plans to make a rare visit to the southern border Thursday − the same day former President Donald Trump plans his own border stop − to call Republicans out for blocking border legislation. Biden will visit Brownsville, Texas, a White House official said, to meet with Border Patrol agents, law enforcement officials and local leaders. Trump, the front-runner to win the Republican nomination, had already scheduled a visit Thursday to Eagle Pass, Texas, about 325 miles away from Brownsville. Biden's trip − the second to the border of his presidency − comes as record migration at the U.S.-Mexico border remains one his biggest election liabilities.
