Senate negotiations on border and Ukraine aid to resume

The conversations will be held remotely.

Bipartisan negotiations resume Wednesday between senators on a potential border security package, a source familiar confirms.

ABC News is told the conversations will be held remotely as the Senate is out on recess for the holiday and is not expected to return until Jan. 8.

Before leaving town last week, principal Senate negotiators signaled they were making "progress" on a potential deal and that they would continue discussing it during the recess.

Democrat Sen. Chris Murphy, GOP Sen. James Lankford and Arizona independent Sen. Kyrsten Sinema -- the trio leading the talks -- had been huddling for weeks to try to find a way forward on changes to immigration and border security.

Details on what could be in a potential border security package are still slim, but the main areas of discussion include: toughening asylum protocols for migrants arriving at the U.S.-Mexico border, bolstering border enforcement with more personnel and high-tech systems and deterring migrants from making the journey to the US in the first place.
