GWEN IFILL:

Rescue and recovery crews on the ground in Washington State are struggling against tough conditions and a forecast of more rain. The mudslide happened about 50 miles northeast of Seattle in the small town of Oso.

Jeffrey Brown has this update.

The National Guard joined the efforts earlier this week.

Master Sergeant Chris Martin is a member of the search and extraction team. He joins us from Arlington right near the site of the mudslide.

Well, thank you for joining us.

So, what is the situation there today? Has it gotten any easier to do the work?
