Another huge crowd tonight in Portland, including a new "wall" on the front lines: a Wall of Vets.

Here's a look at the line of military veterans getting set up here in front of the federal courthouse. Behind them, the Wall of Moms and the Wall of Dads are arriving.

Here is Marine Corps veteran Duston Obermeyer talking about the Wall of Vets.

He mentions Chris David, a Navy veteran that went up to speak with federal officers last week and got brutally hit with a baton.

Army veteran Clint Hall says the federal presence here is wrong. He says it has only served to inflame tensions.

There are also a whole bunch of nurses who are here in blue scrubs.

The overall crowd appears to me to be the largest yet. With the caveat that I'm terrible at estimating crowd sizes, I would guess 4,000 people.

Some strong fence shoving

Pepper balls and tear gas fired.

The feds come out shooting

One of the federal officers appears to have been milkshaked.

Some protesters are working to cut the fence. The feds are targeting them.

Someone took a wrong turn?

Some of the remaining moms have their hands up at the fence

After getting much of their own tear gas blown back at them last night, it looks like the feds went to the hardware store and got leaf blowers of their own.

A surprisingly peaceful stalemate, with both protesters and feds at the fence.

Some are lobbing explosive fireworks over the fence at the feds. Here are two big ones.

This guy has a bag of beans and is throwing them over, a few beans at a time, and saying "Here's your Goya beans."

People are now throwing a lot of water and water bottles. So far, the feds are just taking it.

The feds have now responded with a strategy of casually tossing a ton of tear gas.

Time to play tear gas tennis

Volleys of tear gas and glass bottles

So much tear gas tonight.

Still an ongoing standoff. I'm struggling to stay awake after a week of minimal sleep, so I'm packing it in early.
