A leader with the group that's been raising funds to build a southern border wall on its own says they erected less than a mile of wall on private land in New Mexico over Memorial Day weekend.

Dustin Stockton, co-founder of the nonprofit WeBuildtheWall Inc., told The Associated Press Monday that they spent about 10 days moving dirt before starting construction Friday. 

He said the wall segment in Sunland Park is "mostly up" and should be completed by the end of the week.

Stockton, whose group has raised about $22 million, says they don't have a final tally yet on the cost, but he expects it'll be somewhere between $6 million and $10 million. He says the site's steep incline added to the cost.
