Congressional bargainers are working toward a border security deal amid indications that the White House is preparing to accept a bipartisan agreement that would give President Donald Trump a fraction of the money he's demanded for his proposed southern border wall.

Participants said they expect money for physical barriers to end up well below the $5.7 billion that Trump has sought to begin construction of the wall, which has attained iconic significance for him and his conservative supporters. The amount seems sure to fall much closer to $1.6 billion, the participants said, a figure that was in a bipartisan Senate bill last year.

An agreement would also avert a new partial federal shutdown next weekend.
