WASHINGTON (Reuters) - President Joe Biden will visit the U.S.-Mexico border on Sunday for the first time since taking office nearly two years ago, tackling one of the most politically charged issues in the country as he prepares for a reelection bid.

Biden on Thursday announced fresh plans to block Cuban, Haitian and Nicaraguan migrants at the U.S.-Mexico border, expanding the nationalities of migrants who can be expelled back to Mexico, and the visit to El Paso, Texas, isn't expected to yield any new policy breakthroughs.
