Washington (CNN) Republican and Democratic negotiators are exchanging border security proposals that contain far less funding for the border wall than President Donald Trump has demanded, with just days left before a deadline to release their bill ahead of another potential government shutdown.

The latest proposals peg the topline funding number for border barriers around $2 billion, according to two people familiar with the talks. That number is far below the $5.7 billion that Trump has requested and repeatedly described as the number he wants met, but is in line with where people familiar with the talks thought an agreement may end.

Meanwhile, conservative lawmakers on the board of the House Freedom Caucus met Thursday at the White House with Trump about border security funding, according to a source familiar with the discussion. GOP Reps. Mark Meadows and Jim Jordan were among those at the meeting, which the source described as productive. Freedom Caucus members were among the conservatives who urged Trump in December to shut down the government if he could not secure wall funding at that level.

Rep. Chuck Fleischmann, a Tennessee Republican on the conference committee who touted progress on the talks to reporters on Friday, said GOP conferees are pushing to get the number above $2 billion.

"I want the highest possible number we can get, but I would hope it would be north of ($2 billion)," Fleischmann said.
