President Joe Biden and former President Donald Trump are both set to visit the Texas-Mexico border today. Biden will meet with Border Patrol agents and law enforcement in Brownsville. He's expected to call on the Senate to pass some kind of bipartisan border security legislation. Trump will appear in Eagle Pass to speak on his major campaign theme, which is Biden's failed immigration policies. Eagle Pass is at the epicenter of a struggle between Gov. Greg Abbott and the administration over responsibility for border security.
